Using Q64 to replace GR64


I need to use the Q64 in AT-command mode as a replacement for the GR64. I got garbage when requesting the SIM pin (AT+CPIN?). Is the GR-plugin already installed or do I have to download it to the Q64?


That’s a standard command - so shouldn’t be affected by any plugins?

Do other commands work OK?

Are you sure that you have your terminal settings entirely correct…?

Thanks. I still had the port set to 9600 instead of 115200.
