Hi all,
Does anyone know any libraries that will work for Software serial for the RAK117200? I have 2 uart devices that need to talk to the device, in addition to keeping 1 uart bus free for debugging.
Suggestions for how to do this otherwise would also be appreciated, if you think I should go about this a different way.
Hi @Deanasaur ,
There are two UART available for the RAK11700.
You can access them via Serial and Serial1.
Here’s a loopback test.
Sounds like you need 3 UARTS, 2 hardware UARTs for talking with 2 external devices and a 3rd UART for debugging. I did try other libraries in the past for faking a UART on RAK11720, nothing worked out of the box, you will most likely need a c level bit bang software uart if you need a physically connected debug uart port.
Personally I use the 3rd UART on the RAK11720 for debugging, BLE UART.
