A1102 payload data

Hi
I am using Sensecap A1102 with Chirstack v4 server. On

SenseCraft AI

I Deploy the model Bicycle Detection

I can read the payload but the data look like

        "fPort": 3,
        "confirmed": false,
        "data": "MBIF///8GP///BgyNP///Bj///wYMlb///wY///8GDJ4///8GP///BgzmgX///wYPzKzAA==",
        "object": {
            "payload": "301205FFFFFC18FFFFFC183234FFFFFC18FFFFFC183256FFFFFC18FFFFFC183278FFFFFC18FFFFFC18339A05FFFFFC183F32B300",
            "err": 0,
            "messages": [
                [
                    {
                        "type": "Model Type",
                        "measurementValue": "unknown model",
                        "measurementId": "4174"
                    }
                ]
            ],
            "valid": true
        },
        "rxInfo": [

It seems that the A1102 sends no data …
Any help

This is a wiki tutorial for deploying the model. We hope it will be helpful to you.

Thanks for reply.
I did read this wiki and follow it 5 times but nothing change. I still got the same payload over and over. I was thinking to myself if the firmware is right or the bicycle model is correct … or the A1102 is not working.
Is it possible to go back to the firmware with the 3 modems by default ?
