I just bought RAK3172 and connect with my arduino maker nano. (Total = 3)
Im using P2P mode to communicate between 3 node. (1 master and 2 slave.)
I use 3.3v supply for RAK, RESET High, Uart to Uart arduino, external antenna.
The issue is when I let it send each other for a few minutes, the RAK module stop respond. My arduino LED indicate unresponsive RAK module. Then, I spy on the arduino TX, the data goes out. Then, I spy on arduino RX, no data coming from RAK.
Then I erase arduino program and connect uart cable to directly communicate with module. Module doesnt reply.
Hmmmm. After I restart the module, It reply. Why does this happen. Please help me.
RAK3172 version 21 MAY 2021.
THanks in advanced.
