Looks like they are also using (at least some of) our software stack too, looking at the container names...

[KevinWassermann94]

Not really surprised to see that. Probably 90% of the newer manufacturers are using our stack or parts of it

[shawaj]

Agreed @KevinWassermann94 - just always interesting to see.

Maybe we should get more credit in the community 🤔

Now working at https://nebra.io/pycom

Pycom sx1308 configs here: Archive 5.zip\

Checked these configs against https://github.com/NebraLtd/hm-pktfwd/tree/master/pktfwd/config/lora_templates_sx1301

They are identical and correct on our configs
