AS923

AS923-2 Everynet specifics.

Channels 0 and 1 are fixed and it's mandatory to be implemented on the end-device. Other channels configured by network server using MAC commands during integration stage (after join for OTAA or first uplink for ABP).

Channel Frequency Datarates Type
0 921.4 0,1,2,3,4,5 Fixed
1 921.6 0,1,2,3,4,5 Fixed
2 921.2 0,1,2,3,4,5
3 921.8 0,1,2,3,4,5
4 922.0 0,1,2,3,4,5
5 922.2 0,1,2,3,4,5,6
6 922.4 0,1,2,3,4,5
7 922.6 7 FSK

By default, the RX1 receive window uses the same channel as the preceding uplink.

RX1 timeout = 1s

RX1 datarate offset = 0

The RX2 receive window uses a fixed frequency and data rate. The default parameters are:

921.4 MHz / DR2 (SF10/125KHz)
