GSM Module does not respond
I removed PIN from SIM card, selected IDC mode 2, connected to 24V source and when I run TinyGSM example AT_Debug it says:
"Module does not respond!
Check your Serial wiring
Check the module is correctly powered and turned on"
I tried all the other examples but non of them works. Blue LED on GSM module starts blinking after 1 second push on power button
Hi, can you try with an example modified for Industruino, at https://github.com/Industruino/democode
If you use the 'Serial' port for GSM/GPRS in combination with the INDIO, you have to disconnect 'Serial' from the RS485 port. There is a hardware switch on the baseboard, put it in the upper position to disconnect from the RS485 (away from the RS485 pins).
Please note that the Industruino GSM/GPRS module uses D6 as power on/off pin (it needs 1s HIGH); the relevant lines in the setup() switch the module ON in case it was OFF (or OFF in case it was ON, which can cause some confusion)
