What type of issues is this? [ ] Bug or issue with library functionality - not recognizing the response code

What are you working with? Modem: SIM800C Main processor board: UNO Softserial TinyGSM version: 0.11.5 Code: basic mqtt example

Scenario, steps to reproduce Basic startup , it detects the modem and then goes on the send the AT+CREG? command. The response confirms that the module is connected to the network - +CREG: 0,5 but it stays in that loop until it returns a fail.

Expected result Having a Active MQTT Connection

Actual result Code is stuck in a loop when the "AT+CREG?" is send

Hey, did you end up resolving this issue?

I've had similar issues with my SIM808 with TinyGSM verison 0.11.5

It hangs on checking CREG=0,1

Doing the CIP commands by hand works even with CREG=0,1

The trick was to change the test command to CGREG, in TinyGsmClientSIM800.h line 294:

public: RegStatus getRegistrationStatus() { return (RegStatus)getRegistrationStatusXREG("CREG"); }

To

public: RegStatus getRegistrationStatus() { return (RegStatus)getRegistrationStatusXREG("CGREG"); }
