Add Support for Mikrotik BLE Tags

[sledzik1984]

It would be great to add support for decoding data from Mikrotik TG-BT5-IN and TG-BT5-OUT.
Theese devices are cheap, have accelerometer, temp sensor - great devices for asset tracking with fall detection capabilities.

Data format is described here:

Hi @sledzik1984

Sounds interesting. If you could also supply some example BLE advertising messages of these devices with the option Advertisement and Advanced Data set to true, with whichever integration you are using Theengs Decoder.

Likely best with the native MikroTik telemetry advertising packets.

@sledzik1984

I assume you can build your own Theengs Decoder with new and test decoders included, am I correct?

And I'm a bit confused by the above samples all containing the two octets 0080 for temperature. Could you just confirm at which temperature in °C these were taken - possibly exactly 0°C?

[DigiH]

Either way, have a look at the decoder so far, with temperature, uptime and battery level - I will also add the accelerometer values in the next days …

Updated decoder uploaded … still very puzzled by your (-)128°C temperature.

@sledzik1984

Did you have a look at all at the decoder I created, and can you explain why your samples above give temperatures of -128°C, 128°C or 0°C if masked in post processing?

[sledzik1984]

I will check that today in the evening Od: DigiH ***@***.***> ***@***.***> Odpowiedz: theengs/decoder ***@***.***> ***@***.***> Data: 11 grudnia 2024 at 01:21:54 Do: theengs/decoder ***@***.***> ***@***.***> DW: Piotr Górski ***@***.***> ***@***.***>, Mention ***@***.***> ***@***.***> Temat: Re: [theengs/decoder] Add Support for Mikrotik BLE Tags (Issue #591) @sledzik1984 <https://github.com/sledzik1984> Did you have a look at all at the decoder I created, and can you explain why your samples above give temperatures of -128°C, 128°C or 0°C if masked in post processing? — Reply to this email directly, view it on GitHub <#591 (comment)>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/AAJNCL7RTBBOUBL4YA52P332E6ASDAVCNFSM6AAAAABTF77SLCVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMZDKMZTGMZTGNRWHE> .
