I have tried everything, went through Eddystone protocol… Can’t find the changing Temperature… Here is json example I get : ```auto { "v": 1, "mid": 159, "time": 194, "ip": "10.0.0.103", "mac": "246F28276B84", "devices": [ [ 0, "5ED8B697003C", -55, "020106060956313030530303E7FE09FFC5FE5ED8B697003C" ], [ 3, "ED673856AFC7", -59, "0201060303AAFE1716AAFE00055E005E005E005E005E009BACED673856AFC7" ], [ 3, "ED673856AFC7", -59, "0201060303AAFE1716AAFE00055E005E005E005E005E009BACED673856AFC7" ], [ 3, "ED673856AFC7", -59, "0201060303AAFE1716AAFE00055E005E005E005E005E009BACED673856AFC7" ], [ 3, "ED673856AFC7", -60, "0201060303AAFE1716AAFE00055E005E005E005E005E009BACED673856AFC7" ], [ 3, "ED673856AFC7", -60, "0201060303AAFE1716AAFE00055E005E005E005E005E009BACED673856AFC7" ], [ 3, "ED673856AFC7", -59, "0201060303AAFE1716AAFE00055E005E005E005E005E009BACED673856AFC7" ], [ 3, "ED673856AFC7", -59, "0201060303AAFE1716AAFE00055E005E005E005E005E009BACED673856AFC7" ], [ 3, "ED673856AFC7", -59, "0201060303AAFE1716AAFE00055E005E005E005E005E009BACED673856AFC7" ], [ 3, "ED673856AFC7", -59, "0201060303AAFE1716AAFE00055E005E005E005E005E009BACED673856AFC7" ], [ 3, "31EB9876EB66", -93, "02011A0BFF4C000906030CC0A800A4" ], [ 0, "5ED8B697003C", -56, "020106060956313030530303E7FE09FFC5FE5ED8B697003C" ] ] } ``` How do I get these values to change? to get Temperature? Would appreciate any assistance, thank you! ---

Did you use eddystone-UID protocol? it doesn’t contain temperature value. You should check eddystone TLM protocol instead. Which model of beacon do you use? ---

Hi, thank you for the swift reply! I have tried the protocol yes. But I don’t see the advertising data changing at all… The only hex value changing is the RSSI of that one MAC device. So I am unsure on how I would get the temperature of a bracelet using Eddystone if the HEX is not changing. The model I think is a v100s ? I am also unsure as I did not purchase this and was asked to work on it. But I am stuck and cannot continue with the temperature being static. How would I go about getting the advertising data to change according to the bracelets data? If at all possible, I could send an image of the bracelet instead. ---

You can only get temperature value from eddystone-TLM protocol. Does the beacon support eddystone-TLM protocol? please check with your vendor. ---

Yes I know, and I receive the temperature I think. But I would just like to know why the returned data is always the same. Even if it runs for hours and hours. ---

020106060956313030530303E7FE09FFC5FE5ED8B697003C I get this for 1 braclet… but it is always the same. Never changes and I don’t know why. ---

You can use Android app “nRF Connect” to check the advertising data also. Compare the data ---

Thank you! How would I get said UUID from given json that I receive from gateway? Thank you again ---

Don’t connect the braclet. You should check the advertising data only ---

It’s in the raw data string but that string is much longer than what I get from the gateway, would it possible that the temperature and heartrate is not being sent to the gateway? ---

![image](https://bbs.aprbrother.com/uploads/default/original/1X/63ed3ba675cd9a3ed1cc6c90cef60114582178eb.png) Red is what gateway sends, but yellow is what I don’t have. ---

The length for advertising data is 31 bytes. But the length for your screenshot is 40+ bytes. I think it should plus some other data like scan response data. Which bit is the value of temperature data? ---

It should be ![image](https://bbs.aprbrother.com/uploads/default/original/1X/2f09a4a2aaaa8c0f136a07c00b270eeab81fa108.png) But I am unsure as it does not change. Hence why I would like to know if the data should change? Or if I am just missing something. ---

According to Eddystone TLM though, it says byte 4 - 5 is temp … ![image](https://bbs.aprbrother.com/uploads/default/original/1X/5cfc3495d8ec726b13363f515d72fd7cef4fef63.png) ---

No. It’s not correct. You should check [the prefix for eddystone TLM](https://github.com/google/eddystone/blob/master/protocol-specification.md) first. The TLM data is append to the prefix.
