@rchaudet, Yes, I well know there are physical limitations on this board, however it still appears to me that the software as delivered is not sleeping the primary CPU.
30mA to 26mA does not represent enough of a change for the CPU itself to be going correctly in to sleep, dont you agree?
If fact of that matter is that if the board cannot be slept, then it is of no use. It is quite a trivial matter for development to self-integrate GPS, INS, etc on the a simple module, and a lot more flexible that the dense board as supplied - the only reason for it to be a useful product is if it actually works.
And for it to work, it must be able to sleep at less mA, it is after all conceptually designed as a low power tracker, otherwise what is the point of the onboard LoRa?
I agree that gerber files would be very helpful in working out what is wrong, but again, why use the board if it cannot function as intended. Why have a 'sleep' mode that cannot sleep the board enough to be worthwhile.
