Could’nt connect Xiao Esp32 C3 to LoRa Wio E5 Devkit through AT commands

[Prasadh_P]

Hello I am using Xiao Esp32 C3 and LoRa Wio E5 Devkit to communicate sensor data to TTN using sensecap M2 LoRa gateway.I am using Esp32 C3 as a host MCU to send factory AT commands to Wio E5 devkit to send join requests and also messages through lora.I have used Arduino IDE v3.0.7 to flash Xiao Esp32 C3 with this arduino library for sending LoRa factory AT commands https://github.com/andresoliva/LoRa-E5/ ... me-ov-file

It worked well with Esp32 S2 devkit, I was able to send LoRa messages from Wio E5 Devkit to TTN console thorugh SenseCap M2 Gateway.But when Flashing the same to Esp32 C3, I am not even getting serial output from i don’t know if any other drivers is required for the library I have used.Not Even Serial.Print is comming up when I added it below Serial.begin

When I activated Core Debug Level to Debug mode this is what I have got

Any suggestion on what changes to make or any other libraries to use would be greatly appreciated.
Thanks in Advance…
