专家您好：

cc1350p2 蓝牙传输会自动终止，我们使用的sdk为《simplelink_audio_plugin_3_30_00_06》、《simplelink_cc13x2_26x2_sdk_3_30_00_03》，工程路径C:\ti\simplelink_audio_plugin_3_30_00_06\examples\rtos\CC1352P_2_LAUNCHXL\ble5stack\central_bidirectional_audio、peripheral_bidirectional_audio，附件是log打印。

log提示是没有event。现象是按说明操作后，能够出声音，但很短时间后，log会打印很多warning，声音也随之终止。如果在ble_audio.c文件中的393行，即while (pMsg = Util_dequeueMsg(appMsgQueueHandle))行打断点，可以看到，event的值不包含BLEAUDIO_DATA_READY_EVT、BLEAUDIO_DATA_NEEDED_EVT。

麻烦专家看看，是否是在什么地方配置不对。

同时我修改了ti_drivers_config.h的内容，否则按键无法响应，修改结果如下：

/* LaunchPad Button BTN-1 (Left), Parent Signal: CONFIG_GPIO_BTN1 GPIO Pin, (DIO13) */
#define CONFIG_PIN_BTN1 0x0000000f
/* LaunchPad Button BTN-2 (Right), Parent Signal: CONFIG_GPIO_BTN2 GPIO Pin, (DIO14) */
#define CONFIG_PIN_BTN2 0x0000000e

看起來是你的BLE連線不穩定一直中斷造成,你是用TI LaunchPad測試的嗎?兩個模塊間的距離多遠?

TI LaunchPad-cc1352p-2 Rev.b；非常近，都是放在桌面上，
打印这条log的时候，iis是工作的
#000010 [ 4.876 ] INFO: (ble_audio.c:517) Audio service discovery completed on 0 connection handle,
再按一下右键，打印这条log的时候，会出声音，但是不久后就停止了，iis的时钟随之消失

从报错看，确实怀疑测试环境不好，因为有多个missed event报错。如果可以的话，换一个噪音干扰等少一些的环境。

建议查一下蓝牙连接断开的原因，PeripheralAudio_processGapMessage里的 case GAP_LINK_TERMINATED_EVENT ，位于peripheral_bidirectional_audio.c 文件。连接终止的原因可在结构体gapTerminateLinkEvent_t中找到

可尝试的方法如下：
1、加大supervision timeout的值：GapInit_setPhyParam((INIT_PHY_1M | INIT_PHY_2M | INIT_PHY_CODED),
INIT_PHYPARAM_SUP_TIMEOUT, 100); // defualt value is 100 ms => set it to 1000
2、加大 connection interval的值：修改DEFAULT_MAX_CONN_INTERVAL, DEFAULT_MIN_CONN_INTERVAL, DEFAULT_CODED_MIN_CONN_INTERVAL, DEFAULT_CODED_MAX_CONN_INTERVAL

专家你好：

按照您的提示，我抓取了相关信息，如下图所示，central、peripheral的值各不相同，分别是0x13、0x16。根据在ll.h中的注释说明我无法判断原因，您能否帮忙看看？

0 Maokun.Liang 3 年多前回复 Viki Shi

Intellectual 575 points

同时，按照您给的尝试方法，加大DEFAULT_MAX_CONN_INTERVAL, DEFAULT_CODED_MAX_CONN_INTERVAL的值， DEFAULT_MIN_CONN_INTERVAL, DEFAULT_CODED_MIN_CONN_INTERVAL的值保持不变，DEFAULT_MAX_CONN_INTERVAL, DEFAULT_CODED_MAX_CONN_INTERVAL的值越大，连接的时间越久，但声音越差。

是否可能是数据量比较大，传输速率不够导致的呢？我本想改变传输速率，但是发现该工程配置速率的方法不是按照SmartRF Studio 7的导出.c、.h文件的方式配置，对此还得您指点一下。

根据报错，我还是怀疑环境嘈杂问题，请看这边类似解答：

经过测试，在干扰少的情况下，以及两个板子贴着放的情况下，连接的时间能长很多。但是，我们这边有其他的蓝牙芯片，并不会出现这样的问题。在您给出的链接中，提问者提到用旧版本的工程也不会出现这样的问题。
“
BTW, I also tried ble audio examples from github repo(github.com/.../ble_examples.git) "ble_examples\examples\rtos\CC2640R2_LAUNCHXL\bleapps\central_bidirectional_audio\", under tag "simplelink_cc2640r2_sdk-2.20.00.00", seems that example works stable on cc2640r2 launchpad (under same conditions).

hi Viki，
1352支持1G和2.4G，之前一直在用它的1G，信号稳定。使用2.4G的时候很自然的认为，能和1G的情况一样信号稳定。然而经过实验，我发现1G模式能达到-11dbm，而2.4G模式，即便紧紧的挨在一起，也只能到-30dbm，稍微远一点就是-40几个dbm了。这个应该是会掉的原因，明天我买上两个天线后继续进一步的实验。
感谢你的帮助，我们爱你。
