Fona MQTT example with esp8266

[kamrulroky]

hello, I am working on a project that includes sim800l accessing adafruit MQTT .it works fine with an arduino .my project need to use esp8266 12E with sim800l. I know esp8266 can be use standalone for MQTT but i need to use it as mcu for gsm module. Fona MQTT example shows this error"Error compiling for board NodeMCU 1.0 (ESP-12E Module)" . I am new to arduino or esp8266 , i hope this is a relevant problem.What am I doing wrong here,is there any alternative way to work with esp8266 with sim800l for accessing Adafruit MQTT?

Hello @Nakul93 , Have you tried to upload mqtt_fona sketch to the nodemcu? I have added esp board on "FONAPlatStd.h " too. but its showing something is wrong with sleepy dog library. here the error message

i have uploaded just the basic mqtt_fona example with the mqtt credentials ,can you help me please , how you get them working properly?

[Nakul93]

SleepyDog lib is not supported by esp8266. Remove the Sleepydog lib and also remove all the Watchdog.reset lines in the code. Then it should definitely work.

Thanks Nakul93, removing sleepy dog does get rid off the error but now the nodemcu resetting itself.

Remove while (!Serial); line from setup and check
