MSP430FR2433: Receiving many error framing characters (0xFF)

Part Number: MSP430FR2433

Tool/software:

Tool: CCS 12.7.1

Hi all!

I'm using two LoRa E32 modules to make a comm where one send temperature/humidity data while the other receives it, wthout sending nothing back.

It was working properly for some time, but later the sender received many framing error characters (0xFF), and the receiver side wasn't receiving data anymore.

Someone that has worked with this hardware have a clue about this? The modules communicate via UART, and I'm using the software trim code in it.

Any help is appreciated!
