Initially the module was powered from the 230V. And no sleep mode was implemented at all. Then I added a 1400mAh LiPo battery and the sleep mode. It was running from the battery ca 11 days. It was expected, because the current draw in sleep mode was around 6mA. I figured out with some measurements, why the current draw was so high. I left an SD Card in it, whic is not needed, but did draw quite an ammount of current. Then the SX1276 radio chip was going to sleep mode, but then I reseted it, and the default mode is I think Idle or so, so it draw also more current then expected. There was also a sensor added to the board that I did not planned to use (DHT), that draw also currrent. So I remvoed it. Now it was down to 700uA. Which was still higher than what I expected. Turnd out that the SX module pulls a pin down, and there was a pull up. Which resulted in ca 640uA. I had to remove the pull up, since I was unable to ask the module to rais its pin.
So now it draws around 56uA. The LIPo was fully charged, and the power is disconnected. Calculations say it should round ca 49 days. Lets see. I expect ca 30% less run time.
And I still have some optimisation left. PIC32 is running at 80MHz, can be slower. And the stack needs around 12s of time to get the measurement and communication down, which can be reduced much further.
