Hello NXP,

 

First of all, thank you for your extensive Thread documentation, it is very helpful

I am working on a design using a KW41-based module (Rigado's R41Z) as a black-box Thread modem, which will be controlled by a host via UART. This raises a few questions :

  • among the binaries provided in the SDK, which one should I flash into the module?
  • which pins of the KW41 will be used for RX/TX/CTS/RTS?
  • are the RTS and CTS lines required anyway?
  • how should the host configure the UART connection (baudrate, parity and so on...)?

 

I will also create a small test board with and USB/UART converter to test a minimalist setup. Where can I find some examples of "raw" UART messages that I can send via putty to check if the module is alive?

 

Thank you for your help.

Best,

 

Armel
