I have 1x rak3172 module, and I’m testing the last available firmware v4.0.6, and I have done the comparaison with the 3.4.11:
The downlink with the firmware 3.4.11, and the class C, from my gateway (milesight UG56) is working well (I’m receiving the payload of the downlink few seconds after the sending). I don’t receive anything with the firmware 4.0.6, with the same configuration (I can receive with TTN, but with class A behaviour (in RX1 period)).
The multicast (class C firmware 3.4.11), is also working well (reception by the rak3172 few seconds after). But I can’t configure it for the class C (after join): AT+ADDMULC=C:01020304:01020304050607080102030405060708:01020304050607080102030405060708:869525000:0)
perhaps I misuse the API RAK RUI.
I have searched without success into the forum some duplicates topics.
The firmware 3.4.11 looks to be a stable revision (before the 4.0.6), is it right (or is it the 3.4.2) ? I have notice in the forum that a 48 days bug is present for the 3.5.x revisions, and firsts 4.0.x revisions. Do you know if this bug is also present for the 3.4.11 firmware revision ?
I think I have found why: TTN use the non standard frequency 869525000 for the RX2 (Frequency Plans | The Things Network), perhaps this why, the rak3172 doesn’t receive anything. The milesight gateway was initialized also with the same default frequency value for the EU868 RX2 for Class C …
I have changed to the frequency 868500000, and in this case, it’s working well …
Do the rak3172 filter or check of the downlink frequency ?
For the multicast :
The writing of the multicast configuration looks strange (and/or the display by LSTMULC). I don’t receive anymore unicast messages (of the Class C) after adding the multicast configuration, and the return of LSTMULC looks corrupt :
AT+ADDMULC=C:01020304:01020304050607080102030405060708:01020304050607080102030405060708:868500000:0:0
OK
AT+LSTMULC=?
