RAK3172 and UART 2 along with SUBGHZ

[NimitVachhani]

Greetings Everybody,

Since few months i have been trying my hands on RAK3172. I have successfully implemented ADC, UART/USART and I2C on RAK but without SUBGHZ and everything is working fine.

I have also made my custom code for RAK3172 SUBGHZ and it is also working fine. I have established communication with two RAK3172 modules and they are communicating with each other as on successful data transfer between the two i am toggling LED connected to one of the GPIOs.

Now problem comes when i am enabling UART/USART and SUBGHZ code. On startup i am sending 64 bytes of data out on UART/USART connected to USB to TTL converter. On every power ON i am trying to find 64 bytes of data on terminal but without any successs.

Is there anything that i am doing wrong ?

Hello @NimitVachhani ,

Check if your issue is related to known issue in the following errata.

Ensure system clocks are initialized first and initialize SUBGHZ peripheral before clock changes. Check also the interrupt priorities in your code.
