Dragino LoRa Shield sleep mode

[emailarmin]

Hello,

I am using Dragino LoRa Shield v1.4 for local communiciation between the location of my bee keeping activity and my home, and everthing works fine.

But I have no idea how to put de Dragino LoRa Shield in sleep mode, to reduce the energy consumtion.

Any suggestions?

I would doubt there is a sleep mode for the shield itself.

Most of the LoRa libraries will include functions to put the LoRa module itself into a circa 1uA sleep.

However if that shield is used with a UNO, that will not go into a very low current sleep, so you might as well leave the LoRa module as is.

Hello,

In reality, I use it recently with ESP32, because of its capacity of Wifi functions.

I use the standard library <LoRa.h>, but I do not find any functions for sleep modes.

If ESP32 goes to deep sleep, the shield does not follow this automatically, I think ??

For the documentation on that library, select 'Documentation' from here;

https://www.arduino.cc/reference/en/libraries/lora/

That page has a link to the API;

https://github.com/sandeepmistry/arduino-LoRa/blob/master/API.md

Where you will find a 'sleep' function.

Only the ESP32 would go into deep sleep, but that can be quirte high on a lot (most) boards with ESP32s on them, so test that 'deep sleep' current before worryin about the LoRa device.

A well designed ESP32 powered board can have a deep sleep current in the 25uA region, but that is rare .......
