Please follow the instructions to find out if this device sends passive BLE advertisements. You now gave the gat characteristics, which requires a connection (which isn’t possible with BLE monitor)

[Liionboy]

is ok now?

[Ernst79]

Yes, this is ok, thx. I will look into it in the coming days

[Ernst79]

So, a first analysis. I see a lot of messages which are exactly the same. These start with 0f

0f1650fd490000089eabd33c3c82484a

And I see some changing messages, which start with 14

141650fd488040000019b90572388ac9828c9534ad
141650fd488040000019bbf161d23dbd4d548f0100
141650fd488040000019be9281e5fba46a29be295f

So, most likely, the last messages are the messages with the data.

14 = data length (in hex)
16 = uuid 16 bit
50fd = UUID (0xFD50 = Hangzhou Tuya Information Technology Co., Ltd)
488040000019b90572388ac9828c9534ad = The actual data

488040000019 seems to stay constant.

The last part of the message seems pretty random between the different messages, except for he first byte. (b9, bb, be)
Can't make much sense out of it.

[Liionboy]

i think it was a mistake to buy this thing from Aliexpress, i will buy another with zigbee and support -20 degree.

Thanks for answer

[Ernst79]

Ok, I will than close this issue. Feel free to reopen if you find more information

[hronek]

I have the same sensor. Is there any chance for his support? Would it help to send some information? Which ones? Thanks

[Ernst79]

We can try. Please make a similar log as above, preferably somewhat longer. I will try again to see if I can make sense of it.

Hello, I would be interested to get this temperature and humidity sensor going. THe device is made by Tuya and work with BLE. You can add it in their app. You hold a button to put it in pairing mode, then the app connects to it and gets the temperature and humidity data from it. The device looks to be called TyOS when performing a scan on nRF Connect. The MAC address is DC:23:4F:CE:20:9C. I am not that familiar with BLE packet snniffing. I can't make much sense of the traffic in Wireshark. Here is a hcidump, I hope that it is what is needed. I did capture traffic while opening the tuya app that connected to the sensor and got data from it. The sensor was just in from of the bt usb dongle. Inside the zip is a hcidump file (--raw and written with -w)
dump.zip

I would really appreciate the help, I am willing to provide all the help I can. I have several BT ad BLE dongles, can also capture on android and so on. Thank you

this is the chip from this device, i search but don't find anything compatible with esp

[a-huk]

Why esp, does it require esp

This is some of the data advertized by one sensor:
