CC2640: There is one CC2640 chip, TX transmission failed, but the chip software can be upgraded, the chip has been switched and tested, the fault is removed, so please help to analyze the reason why the chip cannot be sent, is there any points for attentio

Hi xiaofu,

Please be patient as the SimpleLink hardware experts are on leave until January 3rd.  Formal hardware design reviews can be submitted through SIMPLELINK-2-4GHZ-DESIGN-REVIEWS but will have a similar wait time.  Please provide full schematics and board layout including the RF front end.  You can review the LAUNCHXL-CC2640R2F Design Files and SWRA640 to further identify any other reasons for failure. 

Regards,
Ryan

Hi Xiaofu,

Has there been any progress on comparing to the TI design files?

Let me make sure I understand the problem:

1. Can you program and debug the device via JTAG?

2. Can you communicate with the device with SmartRF studio?

3. Can you perform a conducted measurement with a spectrum analyzer and see if an output is being produced?

On the schematic shown I don't see your RF section so it's not possible to provide feedback there.

Thanks,

Jake
