OTAA Node - does not get activated #38

Closed nibelungen closed 7 years ago

nibelungen commented 7 years ago

Hi,

thanks to @brocaar for this great piece of work!

I tried to connect a lopy node with OTAA (https://github.com/pycom/pycom-libraries/blob/master/examples/lorawan-nano-gateway/otaa_node.py) to a single channel gateway (https://github.com/tftelkamp/single_chan_pkt_fwd with http://wiki.dragino.com/index.php?title=Lora/GPS_HAT). So far connection between node - gateway and gateway-bridge works fine, but i think the node does not get the acitvation message it still sends join requests and the gateway bridge always replies with join accept:

That happens multiple time each minute:

Did is miss something? Maybe some one use the same libraray and has success?

Loraserver Loraappserver and Loragatewaybridge AND single_chan_pkt_fwd run on the same rpi.

Thanks in advance, best regards Andreas

.... if this is the wrong section and would be better placed in loraserver section - please let me know!

Definitely I have no idea of what is going on, however.

Do you run also the MQTT server somewhere?

nibelungen commented 7 years ago

All is running on the same rpi. I think the single chan pkt fwd is not capable of OTAA due to the lack of TX function?

From the Readme: Features: listen on configurable frequency and spreading factor SF7 to SF12 status updates can forward to two servers

Not (yet) supported: PACKET_PUSH_ACK processing SF7BW250 modulation FSK modulation downstream messages (tx)

Not (yet) supported: downstream messages (tx). That looks like your issue 😉

Thanks for your reply @brocaar :) Thats my last suggestion too - i switched ABP as a workaround but i now stuck at the received data... It looks like it is encrypted, im using the pycom lora node code. So i have to search for a solution. But for this issue it is definitly no lora-gateway-bridge issue!

Please note that all data is published decrypted to MQTT by LoRa App Server https://docs.loraserver.io/lora-app-server/integrate/data/. However you need to base64 decode this.
