'ERROR' responce for AT commands from A7672

Using Arduino Programming Questions
1

Hello Experts,

I am trying to use SIMCOM A7672S module with ESP32 & I had connected everything properly with sufficient power supply.

The issue I have is that when I send any AT command from ESP32 to A7672S then I recieve 'ERROR' as responce...

Like I sent 'AT', then I gets ERROR as responce...

When I make a call from My mobile to A7672 then the A7672 shows incoming calls, but when I send 'ATA' to recieve the call then again I get responce 'ERROR'...

Please help me with my issue...

Thanks & Regards!!!

Since you’re getting incoming notification messages, I’d start looking at the serial data format. Typically 8N1

I changed the 'No LINE' Option in serial monitor to 'New LINE' & it started working...

I don't know what does mean but it worked...

Thanks for your valuable help..

Thanks & Regards!!!
