I am a beginner on Lora, and it’s been a few weeks that I try to have a low consumption while having the possibility to detect the reception of messages.
I tried with the sandeepmistry library and I can reach 1uA in sleep mode but if I understand correctly, we can’t be notified when we receive messages in sleep mode but in idle mode we can. 1,6 to 1,9 mA on standby mode which is too much.
But unfortunately this library does not offer idle mode (standby and sleep only).
Before I completely abandon the mission I was wondering if someone could confirm me that it is not possible or if it is possible to help me with any library that can do it preferably with Arduino.
I use the sx1276 module and according to the datasheet it would be possible (IDDIDLE):
And looking this official video about low consumption I did nod head anywhere about the idle mode, that make me think it may not be possible.
I’m not using LoraWan I just need sending message between 2 Lora powered by a coin battery CR2032, so few uA as consumption should be good to stay at least 1 year.
