Original question:

CC3135MOD: UART for Radio test tool

CC3135MOD: UART for Radio test tool

Part Number: CC3135MOD
Other Parts Discussed in Thread: CC3135, CC3235SF,

Hi Team, 

 

My customer has a old design and need to pass RF test. 

Now, 2-wire UART is designed.

Base on SimpleLink Wi-Fi® CC3x20, CC3x3x Radio Tool User Guide, it says it need 4-wire UART or SPI.

 

Please help to check if it is possible to use 2-wire UART for TI  Radio Tool.

    Hello,

    Sorry for the delay here. Has the customer tried using RT and was unsuccessful with 2 wire UART? Unfortunately, I believe 4 wire UART should be used here to work with TI Radio Tool.

    Best,

    Josh

    Hi Josh, 

    May I know RT means Radio Tool? 

    If it means Radio Tool, my customer has tried use Radio Tool  w/ 2 wire UART.

    Hi Josh,

    If the TI Radio Tool is not used, does TI provide any example code or documentation to help customers perform RF testing via 2-wire UART?

    We’re looking for alternative methods to support RF testing in production environments where the Radio Tool may not be applicable.

    Appreciate your guidance on this.

    Best regards,

    Hi,

    If you have connected your main MCU to CC3135, you can implement radio testing features into your main MCU firmware. For more details see files radiotool.c/.h in \Source Files\Source Projects\radiotool_CC3235SF_LAUNCHXL_tirtos_ccs\ inside radio tools installation directory. This files are for CC3235, but sl_ API call implementation for CC3135MOD will be exact same.
