@jcaron Thanks for reply. I'm using a private network with Chirpstack and Laird gateway. Yes I know not to use Class C when in deepsleep. Our network is not used in winter (vineyard irrigation) and during this down time we want to sleep our nodes to save battery drain as we have low solar radiation in winter also. We are therefore not sending/receiving messages when in deepsleep. We have been successfully running Class C with 60 nodes for over 2 years, our only issue has been battery life which we are now trying to address. I will try and capture gateway log and post back here. Thanks

Hello @jmarcelino I have currently set up a nano gateway and several nodes (with LoPy) on the 868MHz using the EU868. From what I understand, AS923 is supposed to be used, but there are no strict regulations on the frequencies around 868MHz as of today. It would be better to work on the 923MHz frequency, thus I am currently wondering if anyone has gotten any success on 923MHz, or AS923. When I tried to replicate the EU868 to the AS923, I couldn't get the TTN to display any values other than a random value to pop up only once. I was wondering if anyone with success or failures can share their experience.

So this should do it, acknowledging that no channel willever use AS923 data rate 0 or 1? for channel in range(0, 15): lora.remove_channel(channel) lora.add_channel(0, frequency=923200000, dr_min=0, dr_max=3) lora.add_channel(1, frequency=923400000, dr_min=0, dr_max=3) lora.add_channel(2, frequency=922200000, dr_min=0, dr_max=3) lora.add_channel(3, frequency=922400000, dr_min=0, dr_max=3) lora.add_channel(4, frequency=922600000, dr_min=0, dr_max=3) lora.add_channel(5, frequency=922800000, dr_min=0, dr_max=3) lora.add_channel(6, frequency=922000000, dr_min=0, dr_max=3)

I'm registering my interest in AS923 support. Many of the telcos in AU and NZ are implementing AS923 and will not support devices based on LoPy in its current state of affairs. We're going to have to ditch the LoPy and go with muRata or Multitech modules unless the firmware is updated to give more control. Is this on the cards?
