A6 and ESP32 error with thingspeak #66

Closed Mr-HaleYa closed 4 years ago

Mr-HaleYa commented 4 years ago

I'm using an A6 GSM module and every time I go to write data to Thingspeak I get an error

Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled. Core 1 register dump: PC : 0x400d12b8 PS : 0x00060130 A0 : 0x800d2ca0 A1 : 0x3ffb1f30

I used Exception decoder to decode the error and got this

Is thingspeak the library at fault for my error?

v-c commented 4 years ago

Based on the espressif documentation: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/fatal-errors.html it looks like you may be passing incorrect inputs to the function which is trying to access memory space it isn't allowed to.

Are you sure the inputs to the function call to the ThingSpeak library are correct?

Mr-HaleYa commented 4 years ago

Hahaha, I totally forgot to define thingspeak in the setup so it was panicking when I called a function that had no memory allocated to it... oops... The problem has been soled and can serve as a reference for future people to remember to call all the parameters that you need in setup.
