Hi @mikeyd0407,
It seems it was a soldering issue on the other components on the PCB.
I started checking the other components I have on the board. I removed one by one until the problem is fixed. I found out that 2 components could be the reason of this behavior. So, I removed them and soldered them back and it seems like it worked.
I don’t believe it is an issue with the LORA-E5 chip, but when heating up the PCB to change the LORA chips, the other components on the board might have moved or got a bad solder connection.
I have now 5 boards that are working fine and the solution was, as I said, re-soldering the surrounding components.
I hope this was the case. I have ordered a new batch of boards (with the LE chip) and I’ll test it without changing anything on the PCB 
Best regards,
Vinicius
