S2D not joining Echo Plus ZigBee coordinator

I’m beginning to prototype a Zigbee router/end-device using the S2Ds from my ZigBee Mesh Kit. I’m trying to use an Amazon Echo Plus as a coordinator. To start, I’m following the examples of others who managed to get S2C Xbees talking to SmartThings hubs :


I’ve also found a post from someone who was able to get an S2C to join an Echo+ coordinated PAN :


I’m using the usual HA ZigBee settings on the S2D for a router:

ID 0
CE 0
ZS 2
AP 1
AO 3
EE 1
EO 2
KY 0x5A6967426565416C6C69616E63653039

I put the Echo+ into discovery mode and issue a reset to the S2D, but it never finds a PAN. I’ve tried playing with some of the other firmware options but nothing seems to allow me to join. Has anyone had any luck with an Echo+ coordinator? Or am I maybe missing a crucial setting on the S2D?

Thanks, Kristian

I’ve dug a bit further by enabling verbose join. It appears I am seeing beacons from the coordinator, but these are immediately followed by “Reject ZS” status frames. Here’s an example of what I’m seeing:

Extended Modem Status (API 1)

7E 00 11 98 04 FF B4 9B D2 0B 01 3D 13 44 83 0D 11 40 80 02 40

Start delimiter: 7E
Length: 00 11 (17)
Frame type: 98 (Extended Modem Status)
Status: 04 (Beacon Response)
Status Data: FF B4 9B D2 0B 01 3D 13 44 83 0D 11 40 80 02
Checksum: 40

Extended Modem Status (API 1)

7E 00 02 98 05 62

Start delimiter: 7E
Length: 00 02 (2)
Frame type: 98 (Extended Modem Status)
Status: 05 (Reject ZS)
Checksum: 62

I believe the beacon frame indicates that the Echo+ coordinator is open to join and supports ZS=2. I have ZS=2 set on the S2D. If I’ve understood correctly, it’s the S2D that is rejecting the beacon, although I’m unsure as to why. Might anyone have an idea?

Thanks, Kristian

Hi Kristian,
i am in the same conditions as you. I’m looking for the solution. At the moment I can’t help you.Do you have news about it ?
I request support to DIGI but at moment i d’ont receive any suggestions.

Hi Luca and Kristian, I’m in the same situation, did you find a solution?
