Heltec CubeCell - part 2

@TIS

So far I didn’t succeed combining the sketches LowPower_WakeUpByTimer.ino and LoRaWan.ino until I came across the February 8th posting of bluejedi (see attachment). It would be great if the sketch would automatically go into deep sleep like bluejedi described.

Unfortunately I cannot check if ithis is correct

Why are you not able to check that LoRaWan.ino enters deep sleep automatically?

I cannot check if this is correct, can someone confirm that to me?

Do you want someone to confirm that you cannot check?

do you bluejedi have more information about this?

More information is right below the post that you referenced:

Heltec CubeCell - part 1

I did a small test with the standard LoRaWAN.ino example. When powered by LiPo battery via the battery connector the CubeCell board uses only 8.5 uA during deep sleep! When externally powered directly on the 3.3V pin, either by LiFePO4 (3.2V nominal) or by two Alkaline batteries (2 x 1.5V = 3.0V nominal) the CubeCell board uses only 3 to 3.5 uA in deep sleep.

There is not much more to add to that. I just used the example and measured current during operation.
It’s been quite a while since I experimented with CubeCell. The version of the CubeCell Arduino core and the example may have been updated since but I assume that it will still work like the version I tested. You can find the LoRaWan.ino example in the Arduino packages/CubeCell/hardware/CubeCell/<version>/libraries/LoRa/examples/LoRaWAN/LoRaWan folder.
