UART port passthrough mode

Please advise how can I use UART port passthrough in lora mode?

Hi @leonopulos ,

We have a mode called data transmission mode. This can b the passthrough you are looking for. You can find it in the interface AT command section of the docs.

But this mode is only supported in LoRaWAN mode and not in LoRa P2P.

where can see example of using?

No example available, RAK4200 is EOL for several years already.


To set UART1 into data transmission mode.


to UART1, it will be transmitted over LoRaWAN as binary payload 0x30, 0x42, 0x12, 0x09

To go back to AT command mode send
