RFM95W / Arduino doesn't enter sleep mode after sending packages

Hi there,

I'm currently working on a low power Atmega328 with an RFM95W Module, sending packages with the module works fine. The attached code works, however I'm having issues putting the Atmega328 back to sleep. After power up the board draws some µA, after connecting INT0 PD2 to GND the Lorawan packet arrives. The issue is that after sending the packet the atmega328 doesn't go sleeping. It draws around 4mA in this state. Way to much for a battery application. Can someone help me with this issue?
thanks a lot.

Is this for use on The Things Network, ie TTN ?

Yes it is.

Have you read the fair access policy ?

revert the old code and go sleep at the end of EV_TXCOMPLETE
