Hi @Bartvelp, The `delay()` functions are used quite often in the driver to manage the delays for establish GPRS communication and so on. I made some experiment with the `avr/wdt.h`...

Hi, At the moment, there is no plan to implement MQTT protocol in the driver. I took good note of your suggestion ;-) KR

Hi @ankitmhatre, you are free to contribute ;-). There are some ideas to implement it in issue #30.

Hi @mitiay7, The header part has been implemented by @ztaras and I never had the need to use header in my applications. In the pull request (https://github.com/ostaquet/Arduino-SIM800L-driver/pull/25#issuecomment-725900615), there is some...

I didn't see any buffer limits in this part of the code. The message buffer is defined at the initialisation of the driver (constructor `SIM800L::SIM800L(...)`). What is the message buffer...

Hi @dimitris1965 It should work. However, some adjustment maybe needed to inform the watchdog that the process is still running. Some `sleep()` functions could not be appreciated by the watchdog...

@lackdaz Load resistance with 3.3V is answered in #54

Do you have the datasheet for this breakout board? I see a potentiometer, probably to setup the load resistance (RL) but without details, it is complex to answer.

Hi @NXTkoji, The high concentration sensor is manufactured with a detection range from 10ppm to 1000ppm (and not ppb ;-) ). If you are performing measurements in clean air, I...

@EndruK had a communication issue with the module and it solved it by forcing the baud rate for the AT communication. I planned to integrate his suggestion in the library...
