Help needed with ABP activation

ChirpStack Application Server

Hi there

I’m having some trouble with ABP activation.
Using a Kerlink Ifemtocell and lora server 3.3.0-test.2 AU-915-928
enabled_uplink_channels=[0, 1, 2, 3, 4, 5, 6, 7]

Same node, if configured with OTAA works like a charm.
When using ABP, I just received ONE ping on gateway live data like this one:

{
  "result": {
    "uplinkFrame": {
      "txInfo": {
        "frequency": 916400000,

          ]
        },
        "mic": "85b8550f"
      }
    }
  }
}

My device, shows join was ok, but on network server, nothing happens, even Last seen is showing a day ago.

My Divide profile is set as:

LoRaWAN MAC version *
1.0.3

LoRaWAN Regional Parameters revision
A

Max EIRP
0

Geolocation buffer TTL
0

Geolocation minimum buffer size
0

RX 1 Delay
1

RX1 data-rate offset
0

RX2 data-rate
8 (tried 2 too)

RX2 channel frequency (Hz)
923300000

Factory-preset frequencies (Hz)
915200000, 915400000, 915600000, 915800000, 916000000, 916200000, 916400000, 916600000

I will need to let users activate OTAA and ABP.

Any help is really appreciated.

Thanks

Why would it say that? There’s no such thing as an ABP join

“fCnt”: 0,

What keys are you using? If they have been previously used, then seeing fCnt 0 again is likely to be rejected as a replay attack. Implementing a proper LoRaWAN node requires keeping track of the last used fCnt and making sure it only increments, never rewinds.
