I have reviewed several projects that use this and other similar SIM boards to send data to Iot sites (thingspeak, freeboard, etc). Everyone else seems to be able to do it except me. I hope its not some small stupid detail but I feel like it is.
Original project link: https://openhomeautomation.net/monitor-data-arduino-fona
I had initially tried using a "Adafruit Feather 32u4 FONA" but that didn't work, supposedly because the 2G network's data band was too weak.
Then I moved to the "Adafruit FONA 3G" with the SIM5320 chipset.
I am using a Hologram SIM Card (as indicated by previous project guidelines) It is active and has sufficient funds for data usage beyond 1MB (1MB is provided free).
I plan to attach a sensor to the board in future, but for now I have the data set to some numbers just to test that it will send.
Code is attached, below is the readout from the serial monitor showing errors at the bottom.
Any help would be greatly appreciated.
