HardwareSerial Serial2(2);
#define SerialAT Serial2

The example AT_Debug isn't wrok return.

 You can now send AT commands
 Enter "AT" (without quotes), and you should see "OK"
 If it doesn't work, select "Both NL & CR" in Serial Monitor

and the blynk example isn't compiling.

For the Blynk library - please post an issue on Blynk library github page.

@0x1abin is this issue specific for TinyGSM library? Are you able to send AT commands manually (or using any other example sketch)? If yes, please provide any working example sketch (non TinyGSM-related).

[vshymanskyy]

@0x1abin I need your help to understand the issue.

Closed due to lack of interest

I can confirm the exact same issue. ESP32 with N590 connected to HardwareSerial on pins 32/33.

When using a simple sketch, which only sends data back and forth between the default serial console (USB) and the HardwareSerial, everything works properly.

With the TinyGSM library, a lot of random characters show up during the communication, rendering all results unusable.
