RAK811 - LA915A Channel Plan for Brazil

Hello, please help me, I’m using a RAK811 module and I’m trying to connect to the American Tower LoRaWAN Network (ATC - everynet). Everynet implementation of AU915-928 channel plan for Brazil with LA915A chanel plan. What firmware version or what do I need to do so that my RAK811 end device can use the frequencies and settings below:

Uplink channels.
Index Frequency Datarates
0 915.2 0,1,2,3,4,5
1 915.4 0,1,2,3,4,5
2 915.6 0,1,2,3,4,5
3 915.8 0,1,2,3,4,5
4 916.0 0,1,2,3,4,5
5 916.2 0,1,2,3,4,5
6 916.4 0,1,2,3,4,5
7 916.6 0,1,2,3,4,5

Downlink channels.
Index Frequency
0 923.3
1 923.9
2 924.5
3 925.1
4 925.7
5 926.3
6 926.9
7 927.5

Downlink frequency actually not written in sources, but computed on RX1 window setup as follow:

923300000 + (uplink_channel_number% 8) * 600000

RX2 window channel is fixed:

Frequency: 923.3 Datarate: 8

Receive delay for RX1 window: 5sec

Receive delay for RX2 window: 6sec

Default uplink dwell time: 0

Default downlink dwell time: 0

Thanks,

Hi @wmf, there is no specific firmware version of RAK811 that supports LA915A frequency plan yet.

I checked the everynet website link you provided but the links inside are broken. You need to contact everynet for those info because those details are important for you.

The modifications on the Loramac stack is there. Which can give you clue on what to modify. Then you can build your own firmware based on those Loramac stack modifications.

Here’s a guide on how to do low-level development with RAK811.

Hi @carlrowan, thanks!
