HI! I am actually working with the library for arduino of RAK811 modem, for second band of us915 frecuency and ABP mode. The module works fine; but i have some doubs about "fCnt". The fCnt that i receive is always on "0". I think that maybe one of the next commands maybe restart the counter:
2- at+set_config=dev_addr:" + DevAddr + "&nwks_key:" + NwkSKey + "&apps_key:" + AppSKey?
can you tellme wich are?
I've tested with the latest firmware and the consumption current is less than 10 uA (7.7 uA after a few minutes increase to about 8.9 uA) with supply voltage 3.3v. It seems that the current consumption can be reduced more by using the standby mode instead of stop mode.
