Unstable MQTT with SIM800L #699

Closed garudaonekh closed 1 year ago

garudaonekh commented 1 year ago

HI, I use SIM800L with ESP8266. I use the MQTT Client example code(Rx/TX on pin 4,5).

The GPRS and MQTT keep disconnecting and reconnect.

I test the AT commands individually, it seems fine. For example: AT+CIPSTART="TCP","ttttext.com","1883" is ok and keep connected for 2 minutes before disconnected automatically.

Here's the log

Changing the baudrate from 115200 to 9600 seems to solve the problem. Anyway, at this baudrate, it'll be too slow for download rate.
