LoRaWan APB not working anymore with new firmware ?

[stef]

hi all ,
i was using Apb mode on LoPy 1.6.1 with success .

it's a private Lora with 2 differents gateways for test purpose , an IC880 + Rpi 3 and a MatchX gateway .

I dev a node.js script for decrypting and forwarding packet to server in REST (using lora-packet node library)

Hope solving a BT bug , i flashed one of my loppy to 1.7.9 and now transmitted packet can't be decryted anymore.

is there significant change in APB crypting from 1.6.1 to 1.7.9 ??

here is the difference beetween the two LoPy ( same code , same gateway )

any suggestions are welcome

Just released 1.7.9.b3 which solves the ABP issue. Apologies for this bug, we'll investigate why it was not picked up by our automatic tests.

I can confirm, updating from 1.7.8.b1 to 1.7.9.b2 encryption of uplink and download user payload fails with the same NwSKey/AppSKey key pairs with the same Network Server using ABP.

It is a bug in 1.7.9.b2

I'm not sure it is an official version as it was not yet announced.
