AT+CPUTemp - Githubissues

droidblastnz commented 12 months ago

Sometimes but not all times when using TinyGSM to retrieve the AT+CPUTemp it errors.

Code...

      modem.poweroff();
      DBG("Poweroff Modem!");

      // Wait for modem to power off
      light_sleep(5);

      esp_sleep_enable_timer_wakeup(TIME_TO_SLEEP * uS_TO_S_FACTOR);
      delay(200);
      esp_deep_sleep_start();

      while (1);

Almost like the ESP32 isnt talking to the modem yet the modem is connected online and taken commands?

@lewisxhe any ideas? After sleep AT+CBC and AT+CPUMTEMP error and cannot be read but the modem is taken commands?

droidblastnz commented 11 months ago

Seems to align with AT+CMTE=1 on first boot is fine and sometimes after deep sleep but if CMTE errors then the AT+CBC and AT+CPUMTEMP seem to error.

// Power down when the module’s temperature is over critical temperature 0 – Disable or 1 – Enable temperature detection
  modem.sendAT("+CMTE=1");                                                   //if errors restart due to Deep Sleep ESP32 not SIM7600
  Serial.println("CMTE Critical temperature detection has been enabled!");
  modem.waitResponse(1000);

Setup();
// Power down when the module’s temperature is over critical temperature 0 – Disable or 1 – Enable temperature detection
  modem.sendAT("+CMTE=1");                                                   //if errors restart due to Deep Sleep ESP32 not SIM7600
  Serial.println("CMTE Critical temperature detection has been enabled!");
  modem.waitResponse(5000);
  modem.sendAT("+CMTE?");
  modem.waitResponse(1000);

Note: Pre sleep CBC reads Powersupply voltage correctly

22:35:37.684 -> +CBC: 3.719V

Coming out of sleep CBC reads wrong at 2,0 (comma? not a period!)

08:33:46.171 ->

Although CBC and CPMUTEMP are wrong or not working I can still send commands to the modem via SMS or MQTT and it works as expected.
