Deep Sleep with FiPy / ESP32 on MicroPython

See also. This is the code used to sleep: import machine machine.pin_deepsleep_wakeup(pins=['P8'], mode=machine.WAKEUP_ALL_LOW, enable_pull=True) machine.deepsleep(60000)

All radios on by default

Maßnahmen

WiFi, Bluetooth und LTE, ggf. nur mit SIM Karte.

… oder doch nicht nötig?

@thomand1000
If you don’t actively use the LTE it’s actually better not to deinit() it, don’t call LTE module even. The modem should automatically go into deepsleep mode.

Hi @pierremarsot,

actually, there is no need to disable BT/WiFi or Heartbeat before deepsleep, they are disabled automatically when calling machine.deepsleep. Also the LoRa modem is turned off in deepsleep.

I’ve actually ran you code on a LoPy4 and I get an Avg current consumption in deepsleep = 27uA.

Stromsparmaßnahmen für die MicroPython-Firmware im Batteriebetrieb

Auf Sensorebene gibt es beim HX711 in der C-Bibliothek die Möglichkeit den schlafen zu schicken. Kann das sie uP-lib auch?

Internen LDO abschalten

@Andreas

The internal LDO can be configured as having 1.8 V, or the same voltage as VDD3P3_RTC. It can be powered off via software to minimize the current of flash/SRAM during the Deep-sleep mode.
