I was setting up MQTT using YAT.
I typed one AT command wrong. After this the wifi module is broken.
Cannot reset. Removing power supply and reconnecting is not helping. Is is as if module is dead.
The wrong command I typed is "AT+MQTTTCON=0,“192.168.1.6"1883”
I missed a comma, and there is an extra ‘T’
could you please help recover the module?
