&lt;p&gt;I am trying to use the CC2340R5 with the &lt;code&gt;LP_EM_CC2340R5/prop_rf/rfPacketTx&lt;/code&gt; example as a starting point.&lt;/p&gt;
&lt;p&gt;My goal is:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;p&gt;Use the &lt;code&gt;Custom&lt;/code&gt; RF stack configuration with BLE PHY selected (&lt;code&gt;Generic 1 Mbps / 2 Mbps / Coded&lt;/code&gt;)&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Transmit a fixed custom BLE advertising PDU&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Do not use the full BLE stack (GAP/GATT/LL)&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Later switch dynamically between BLE PHY and other PHYs for a multi-protocol application&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;Currently I can run with the &lt;code&gt;prop_rf&lt;/code&gt; example, but I cannot make a valid BLE advertising packet that can be detected by a phone or nRF Connect.&lt;/p&gt;
&lt;p&gt;I would like to understand:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;When using &lt;code&gt;Custom -&amp;gt; BLE&lt;/code&gt; PHY in SysConfig, does the radio automatically handle:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;p&gt;BLE Access Address (0x8E89BED6)&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;CRC24&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Data whitening&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;BLE bit ordering&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Is it sufficient to provide only the BLE advertising PDU payload:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;
&lt;p&gt;Header&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;AdvA&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;AdvData&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;or do I need to manually construct the full BLE over-the-air packet?&lt;/p&gt;
&lt;ol start="3"&gt;
&lt;li&gt;
&lt;p&gt;Does the &lt;code&gt;rfPacketTx&lt;/code&gt; example use a proprietary packet formatter that prepends packet length or uses a non-BLE packet structure?&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Is there an official example for transmitting raw/custom BLE advertising packets without using the BLE stack?&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;My current intention is to transmit only on advertising channel 37 (2402 MHz) first.&lt;/p&gt;
&lt;p&gt;Thank you.&lt;/p&gt;</description></item><item><title>RE: CC2340R5: CC2340R5 Custom BLE PHY: How to transmit raw/custom BLE advertising PDUs without BLE stack using prop_rf/rfPacketTx?</title><link>https://e2echina.ti.com/thread/3868179?ContentTypeID=1</link><pubDate>Wed, 20 May 2026 08:24:27 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:822bc9b5-94c2-418d-b001-49261456aabc</guid><dc:creator>Qingtian Yang</dc:creator><slash:comments>0</slash:comments><comments>https://e2echina.ti.com/thread/3868179?ContentTypeID=1</comments><wfw:commentRss>https://e2echina.ti.com/support/wireless-connectivity/other-wireless/f/other-wireless-technologies-forum/1073578/cc2340r5-cc2340r5-custom-ble-phy-how-to-transmit-raw-custom-ble-advertising-pdus-without-ble-stack-using-prop_rf-rfpackettx/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;您好：&lt;/p&gt;

 &lt;p&gt;你好，&lt;/p&gt;
 &lt;p&gt;您应该查阅&lt;a href="https://dev.ti.com/tirex/explore/node?isTheia=false&amp;amp;node=A__ALapRB1.9CtY3rT.dYSF0w__com.ti.SIMPLELINK_LOWPOWER_F3_SDK__58mgN04__LATEST"&gt;RCL API 指南&lt;/a&gt;中的&lt;a href="https://dev.ti.com/tirex/content/simplelink_lowpower_f3_sdk_9_20_00_81/docs/rcl/html/ble_command_handlers.html"&gt;BLE 命令处理程序&lt;/a&gt;（例如&lt;a href="https://dev.ti.com/tirex/content/simplelink_lowpower_f3_sdk_9_20_00_81/docs/rcl/html/advertiser_handler.html"&gt;广播命令处理程序&lt;/a&gt;）和&lt;a href="https://dev.ti.com/tirex/content/simplelink_lowpower_f3_sdk_9_20_00_81/docs/rcl/html/commands_2ble5_8h.html"&gt;BLE5 文件参考&lt;/a&gt;。请注意，这需要使用自定义的 ti_radio_config.c/h 文件，因为 SysConfig 目前不支持自定义使用这些 RCL 命令。本质上，rfPacketTx 使用 BLE PHY，但并未公开所有 RCL 命令。您需要进一步研究文档，并尝试调整项目配置及其广播数据包结构，才能获得预期的输出。&lt;/p&gt;
 &lt;p&gt;问候，

&lt;p data-path-to-node="6"&gt;I am excited to see the DMM (Dynamic Multi-protocol Manager) solution implemented in the latest &lt;strong data-index-in-node="96" data-path-to-node="6"&gt;SimpleLink LowPower F3 SDK (v9.20.00.81)&lt;/strong&gt;. I am currently working with the &lt;strong data-index-in-node="170" data-path-to-node="6"&gt;CC2340&lt;/strong&gt; series for an IoT project.&lt;/p&gt;
&lt;p data-path-to-node="6"&gt;Currently, I do not see any ready-to-use DMM examples specifically for the CC2340. Given this lack of reference, I am considering the following approach to implement a lightweight multi-protocol solution that fits within the 36KB/64KB RAM limit&lt;/p&gt;
&lt;p data-path-to-node="8"&gt;&lt;strong data-index-in-node="0" data-path-to-node="8"&gt;My specific requirements and pain points:&lt;/strong&gt;&lt;/p&gt;
&lt;ol start="1" data-path-to-node="9"&gt;
&lt;li&gt;
&lt;p data-path-to-node="9,0,0"&gt;&lt;strong data-index-in-node="0" data-path-to-node="9,0,0"&gt;Lightweight Coexistence:&lt;/strong&gt; I do not necessarily need full-stack features (like a complete Zigbee mesh or high-level BLE profiles). My goal is to achieve basic packet transceiver (RX/TX) functionality across different protocols.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p data-path-to-node="9,1,0"&gt;&lt;strong data-index-in-node="0" data-path-to-node="9,1,0"&gt;Protocol Switching:&lt;/strong&gt; Is it feasible to use DMM on CC2340 to switch between &lt;strong data-index-in-node="74" data-path-to-node="9,1,0"&gt;BLE (Low Level)&lt;/strong&gt;, &lt;strong data-index-in-node="91" data-path-to-node="9,1,0"&gt;802.15.4 (MAC layer only)&lt;/strong&gt;, and &lt;strong data-index-in-node="122" data-path-to-node="9,1,0"&gt;Proprietary 2.4G (RF Driver/RAIL level)&lt;/strong&gt;?&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p data-path-to-node="9,2,0"&gt;&lt;strong data-index-in-node="0" data-path-to-node="9,2,0"&gt;Basic Control:&lt;/strong&gt; I only need to perform basic operations like changing frequencies/channels and sending/receiving raw data packets while maintaining a basic BLE connection for configuration.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p data-path-to-node="9,3,0"&gt;&lt;strong data-index-in-node="0" data-path-to-node="9,3,0"&gt;Demo Availability:&lt;/strong&gt; Are there any &amp;quot;Lightweight DMM&amp;quot; or &amp;quot;DMM + RF Driver&amp;quot; demos available for the CC2340?&amp;nbsp;&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p data-path-to-node="10"&gt;Could you please provide guidance on how to implement such a &amp;quot;bare-metal style&amp;quot; multi-protocol switching using DMM on the CC2340? Or is there a recommended architecture for achieving low-level RF concurrency without the RAM overhead of full-featured stacks?&lt;/p&gt;
&lt;p data-path-to-node="11"&gt;Looking forward to your expert advice.

&lt;p&gt;&lt;span&gt;你好，我在尝试通过寄存器读取RSSI的值时，当我另一台设备开始在同一频段工作发送信号时，当前的设备CC2500读取到的RSSI值从-59dB变成-19dB，但是就一直维持在这个值没有再发生变化了，即使是我关闭了另一台CC2500的设备。请问我应该怎么配置CC2500才能使其可以连续正常的读取RSSI值的变化呢？以下是我相关的配置与代码。[embed:dc8ab71f-3b98-42d9-b0f6-e21e02a0f8e2:2bf1922c-0552-4293-8d34-300f961d7363:type=c_cpp&amp;text=%23define%20CCxx0x_SRX%20%20%20%20%20%20%20%20%20%200x34%0A%23define%20CCxx0x_RSSI%20%20%20%20%20%20%20%20%200x34%0A%0Astatic%20const%20C25RegisterSetting_t%20C25PreferredSettings%5B%5D%3D%20%0A%7B%0A%20%20%20%20%7BCCxx0x_IOCFG2%2C%20%20%20%20%20%20%20%20%20%20%20%200x29%7D%2C%0A%09%7BCCxx0x_IOCFG1%2C%20%20%20%20%20%20%20%20%20%20%20%200x2E%7D%2C%0A%09%7BCCxx0x_IOCFG0%2C%20%20%20%20%20%20%20%20%20%20%20%200x06%7D%2C%0A%09%7BCCxx0x_FIFOTHR%2C%20%20%20%20%20%20%20%20%20%20%200x07%7D%2C%0A%09%7BCCxx0x_SYNC1%2C%20%20%20%20%20%20%20%20%20%20%20%20%200xD3%7D%2C%0A%09%7BCCxx0x_SYNC0%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x91%7D%2C%0A%09%7BCCxx0x_PKTLEN%2C%20%20%20%20%20%20%20%20%20%20%20%200xFF%7D%2C%0A%09%7BCCxx0x_PKTCTRL1%2C%20%20%20%20%20%20%20%20%20%200x04%7D%2C%0A%09%7BCCxx0x_PKTCTRL0%2C%20%20%20%20%20%20%20%20%20%200x05%7D%2C%0A%09%7BCCxx0x_ADDR%2C%20%20%20%20%20%20%20%20%20%20%20%20%20%200x00%7D%2C%0A%09%7BCCxx0x_CHANNR%2C%20%20%20%20%20%20%20%20%20%20%20%200x00%7D%2C%0A%09%7BCCxx0x_FSCTRL1%2C%20%20%20%20%20%20%20%20%20%20%200x06%7D%2C%0A%09%7BCCxx0x_FSCTRL0%2C%20%20%20%20%20%20%20%20%20%20%200x00%7D%2C%0A%09%7BCCxx0x_FREQ2%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x5D%7D%2C%0A%09%7BCCxx0x_FREQ1%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x93%7D%2C%0A%09%7BCCxx0x_FREQ0%2C%20%20%20%20%20%20%20%20%20%20%20%20%200xB1%7D%2C%0A%09%7BCCxx0x_MDMCFG4%2C%20%20%20%20%20%20%20%20%20%20%200x88%7D%2C%0A%09%7BCCxx0x_MDMCFG3%2C%20%20%20%20%20%20%20%20%20%20%200x93%7D%2C%0A%09%7BCCxx0x_MDMCFG2%2C%20%20%20%20%20%20%20%20%20%20%200x13%7D%2C%0A%09%7BCCxx0x_MDMCFG1%2C%20%20%20%20%20%20%20%20%20%20%200x22%7D%2C%0A%09%7BCCxx0x_MDMCFG0%2C%20%20%20%20%20%20%20%20%20%20%200xF8%7D%2C%0A%09%7BCCxx0x_DEVIATN%2C%20%20%20%20%20%20%20%20%20%20%200x34%7D%2C%0A%09%7BCCxx0x_MCSM2%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x07%7D%2C%0A%09%7BCCxx0x_MCSM1%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x30%7D%2C%0A%09%7BCCxx0x_MCSM0%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x18%7D%2C%0A%09%7BCCxx0x_FOCCFG%2C%20%20%20%20%20%20%20%20%20%20%20%200x16%7D%2C%0A%09%7BCCxx0x_BSCFG%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x6C%7D%2C%0A%09%7BCCxx0x_AGCCTRL2%2C%20%20%20%20%20%20%20%20%20%200x43%7D%2C%0A%09%7BCCxx0x_AGCCTRL1%2C%20%20%20%20%20%20%20%20%20%200x40%7D%2C%0A%09%7BCCxx0x_AGCCTRL0%2C%20%20%20%20%20%20%20%20%20%200x91%7D%2C%0A%09%7BCCxx0x_WOREVT1%2C%20%20%20%20%20%20%20%20%20%20%200x87%7D%2C%0A%09%7BCCxx0x_WOREVT0%2C%20%20%20%20%20%20%20%20%20%20%200x6B%7D%2C%0A%09%7BCCxx0x_WORCTRL%2C%20%20%20%20%20%20%20%20%20%20%200xF8%7D%2C%0A%09%7BCCxx0x_FREND1%2C%20%20%20%20%20%20%20%20%20%20%20%200x56%7D%2C%0A%09%7BCCxx0x_FREND0%2C%20%20%20%20%20%20%20%20%20%20%20%200x10%7D%2C%0A%09%7BCCxx0x_FSCAL3%2C%20%20%20%20%20%20%20%20%20%20%20%200xA9%7D%2C%0A%09%7BCCxx0x_FSCAL2%2C%20%20%20%20%20%20%20%20%20%20%20%200x0A%7D%2C%0A%09%7BCCxx0x_FSCAL1%2C%20%20%20%20%20%20%20%20%20%20%20%200x00%7D%2C%0A%09%7BCCxx0x_FSCAL0%2C%20%20%20%20%20%20%20%20%20%20%20%200x11%7D%2C%0A%09%7BCCxx0x_RCCTRL1%2C%20%20%20%20%20%20%20%20%20%20%200x41%7D%2C%0A%09%7BCCxx0x_RCCTRL0%2C%20%20%20%20%20%20%20%20%20%20%200x00%7D%2C%0A%09%7BCCxx0x_FSTEST%2C%20%20%20%20%20%20%20%20%20%20%20%200x59%7D%2C%0A%09%7BCCxx0x_PTEST%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x7F%7D%2C%0A%09%7BCCxx0x_AGCTEST%2C%20%20%20%20%20%20%20%20%20%20%200x3F%7D%2C%0A%09%7BCCxx0x_TEST2%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x88%7D%2C%0A%09%7BCCxx0x_TEST1%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x31%7D%2C%0A%09%7BCCxx0x_TEST0%2C%20%20%20%20%20%20%20%20%20%20%20%20%200x0B%7D%2C%0A%7D%0A%0Aint8_t%20CC2500_Get_RX_dBm%28unsigned%20char%20_ucRssi%29%0A%7B%0A%20%20%20%20int16_t%20sData%3D_ucRssi%3B%0A%09%2F%2F%20%E5%8F%96%E7%BB%9D%E5%AF%B9%E5%80%BC%0A%20%20%20%20if%28_ucRssi%3E%3D128%29%0A%09%7B%0A%09%09sData%20%3D%20%28int16_t%29%28_ucRssi%20-%20256%29%2F2%20-%2074%3B%0A%09%7D%0A%09else%0A%09%7B%0A%09%09sData%20%3D%20%28_ucRssi%2F2%29%20-%2074%3B%0A%09%7D%09%0A%09%0A%09if%28sData%20%3C%20-128%29%0A%09%7B%0A%09%09sData%20%3D%20-128%3B%0A%09%7D%0A%20%20%20%20return%20sData%3B%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%2F%2F%20%E8%AE%A1%E7%AE%97RSSI%E5%80%BC%0A%7D%0A%0Aint8_t%20CC2500_ReadReg_RSSI%28%29%0A%7B%0A%09uint8_t%20nRet%3B%0A%09%2F%2F%20%E8%BF%9B%E5%85%A5%E6%8E%A5%E6%94%B6%E6%A8%A1%E5%BC%8F%0A%09CC2500_Strobe%28CCxx0x_SRX%29%3B%20%0A%09%2F%2F%20%E7%AD%89%E5%BE%85%E7%A8%B3%E5%AE%9A%0A%09delay_ms%281%29%3B%0A%09%2F%2F%20%E8%AF%BB%E5%8F%96%E4%BF%A1%E5%8F%B7%E5%BC%BA%E5%BA%A6%E5%AF%84%E5%AD%98%E5%99%A8%0A%09nRet%20%3D%20CC2500_ReadReg%28CCxx0x_RSSI%29%3B%0A%0A%09return%20CC2500_Get_RX_dBm%28nRet%29%3B%0A%7D]&lt;/span&gt;&lt;/p&gt;</description></item><item><title>RE:

&lt;p&gt;你好，非常感谢您提供的例程，具有很大的参考价值。但是我根据例程在尝试通过寄存器读取RSSI的值时，当我另一台设备开始在同一频段工作发送信号时，当前的设备CC2500读取到的RSSI值从-59dB变成-19dB，但是就一直维持在这个值没有再发生变化了，即使是我关闭了另一台CC2500的设备。请问我应该怎么配置CC2500才能使其可以连续正常的读取RSSI值的变化呢？以下是我相关的配置与代码。&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: CC2500: 其他无线技术论坛</title><link>https://e2echina.ti.com/thread/3677326?ContentTypeID=1</link><pubDate>Wed, 10 Sep 2025 11:36:49 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:5841147b-2fa7-45bb-808e-675f9f0330e3</guid><dc:creator>Z.Cheng C</dc:creator><slash:comments>1</slash:comments><comments>https://e2echina.ti.com/thread/3677326?ContentTypeID=1</comments><wfw:commentRss>https://e2echina.ti.com/support/wireless-connectivity/other-wireless/f/other-wireless-technologies-forum/1024722/cc2500/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;HI,Daniel,the CC2500 acts as both a RX and a TX. When data needs to be sent, it switches to TX mode. After sending is completed, it switches back to RX mode to wait for the other CC2500 device to receive the data and send a response.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
