Issue: RAK4200 Breakoutboard Lorawan TTN v3 connection issue
Setup: RAK4200 breakoutboard + Raspberry pi pico
Server: TTN v3
Details:
Hi all, I am very new to LoRa. I tried to use RAK4200 breakout board with pico as the LoRa end node, but I couldn’t get it work for couple of weeks… I have a gateway successfully connected to TTN in range as image below:
I followed the this guide: Raspberry Pi Pico Lorawan connection using RAK4200/RAK4270 Wisduo Breakout Board
However, I got error like this:
Then I used the RAK Serial Port Tool with UART to USB adapter and followed the official guide: RAK4200 Breakout Board Quick Start Guide #
At first all commands appear to have been sent successfully, but when I send at+ Join, the Serial Port Tool freezes without any response. I tried many times and got stuck sending “at+join”:
Here are all the settings on TTN v3 and the ouput of Serial Port Tool:

I tried my best to search and find solution before I came here to ask for help. But, it’s really frustrating that I could’t even find out where is the issue… Any help or advice would be greatly appreciated! Thank you all in advance!!!
