CC1350 433MHZ时最大数据速率

Other Parts Discussed in Thread: CC1350

需要CC1350的RF详细测试数据,特别是CC1350 433MHZ时最大数据速率

  • • Wide range of data rates:
    – From 625 bps (offering long range and high robustness) to as high as 4 Mbps

    8-FSK调制模式下可以支持最大data rate到4Mbps,可以参考SDK中的 PacketErrorRate 例程: dev.ti.com/.../node
  • SDK中提到在HS mode不支持CC1350(433MHZ),HSM and OOK are not supported on the CC1310-CC1190, CC1350 (433 MHz), CC1352 (R1/P1/P-2/P-4) or CC2640R2 Launchpads
  • 是的,抱歉,之前没看清是433Mhz下的data rate。目前支持的模式及分别的data rate如下:

    Test cases are provided for the following RF modes:

    Custom : Custom settings to be exported from SmartRF Studio to the smartrf_settings.c file
    2-GFSK : Gaussian frequency shift keying with binary symbols, 50 kBit/s for all launchpads, 250 KBits/s for the CC2640R2
    GFSK 200K : Gaussian frequency shift keying with binary symbols, 200 kBit/s IEEE 802.15.4g for all CC13x2 launchpads
    GFSK 100K : Gaussian frequency shift keying with binary symbols, 100 kBit/s (CC2640R2 only)
    GFSK 250K : Gaussian frequency shift keying with binary symbols, 250 kBit/s (CC2640R2 only)
    LR Mode : Legacy Long Range (625 bps)
    OOK : On-off keying
    HS Mode : High-speed mode with up to 4 MBit/s
    SL LR : SimpleLink Long Rang (5 kbps)
    BLE : Bluetooth Low Energy (CC135X, CC2640R2 only)
    BLE5 : Bluetooth Low Energy 5 (CC1352, CC2640R2 only)
    Note that - HSM and OOK are not supported on the CC1310-CC1190, CC1350 (433 MHz), CC1352 (R1/P1/P-2/P-4) or CC2640R2 Launchpads - Legacy Long Range Mode (LRM) is not supported on the CC1352(R1/P1/P-2/P-4). - For the GFSK 200K mode, if transmitting from Smart RF Studio set the PSDU octet transmission order to MSbit First
  • 能否提供433MHZ下速率的详细测试数据或者明确的最大速率?
  • 原理上可以到500kbps,不过实验室还没完成测试,具体请看这边:e2e.ti.com/.../870329
