CC1310: Communication problem with Internet of Things device

Sergey Tarakanov

Part Number: CC1310

I've been developing a device for the Internet of Things on the basis of TI CC1310 chip. Designed software runs OK on TI debug boards - the connection is established, the data is exchanged without any loss.

But when I upload my firmware to the custom designed circuit board I see connection established but no data passed through. Thus, if I connect the circuits using SmartRF Studio from TI and debug boards they are fully functional: RSSI and the number of errors the same as in debug boards. I've checked the transceiver function through the antennas on the circuits, copied from debug board, and by a coaxial cable - the result is identical.

    It's not fully clear to me exactly what does and does not work in your case.

    If I understand you correctly:
    - The software runs on TI evaluation boards without issues.
    - The software does not run as intended on your custom board. What does "connection established but no data passed through" mean?
    - The custom board work controlled by Studio.

    If the above is the case, what type of software are you running? If controlled by Studio, the hardware will not go down in the lowest power states due to the JTag interface is still connected. Does your board have a 32 kHz xtal and if not, have you in the ccfg.c file set the device to use a different LF clock than the 32 kHz xtal.

    What are the differences between your hardware and the evaluation boards?
