Has anybody able to run the platformio Thingsboard example successfully? #196

Open shivanshumahim opened 2 years ago

shivanshumahim commented 2 years ago

I have a SIM800L TTGO TCall. I have chosen Thingsboard IoT platform for a project. The example just doesn't work for me :( I have tested Blynk GSM example and it works fine. I have tested thingsboard via ESP32 wifi, works fine, however GSM + Thingsboard doesn't. No Complication error, just " Could not connect

Serial Output:- (after esp32 wakes up)

IP5306 setPowerBoostKeepOn: OK IP5306 Battery level:100 Battery from ADC: 4195mV In loop MODEM_RST & IP5306 IRQ: HIGH MODEM_PWKEY: HIGH MODEM_POWER_ON: HIGH MODEM_PWKEY: LOW Modem: SIM800 R14.18 The sensor did not respond. Please check wiring. GSM Battery: 0% 0mV IP5306 Battery level:100 Battery from ADC: 4194mV Waiting for network... OK Signal quality:31 Connecting to airtelgprs.com OK Connecting to: demo.thingsboard.io with token 6bh72bChcwDdzKTRKvql Failed to connect GPRS disconnect Radio off GSM power off Going to sleep now

this on loop :(

I was able to connect via HTTP, so will leave the code here, if anyone needs it. My project requires MQTT so i am working on it. Once done, will update here as well.

HTTP code:-
