hi community , i am using nrf52833 ,

my requirement is ,i need to advertise (broadcast)  sensor data with out connecting to nrf52833  in nrf connect app.

i am using beacon eddystone example code as reference but it advartising ULR website ,  i am trying to use TLM frame type ,but not able to send sensor data to the slot.

please suggest any example  or send any reference code  to solve this problem.

warm regards,

Hi Bharath,

Do you know that Eddystone is no longer supported by Google?

See:
android - Is Google deprecating beacon service? Their announcement is ambiguous - Stack Overflow
and
Get Beacon Messages  |  Nearby Messages API for Android  |  Google Developers

I don't really recommend you continue with Eddystone. It is far more complex than necessary for what you are doing.

If you just want to add sensor data to your advertisement, please instead look into Manufacturer Specific Data and dynamically update it.

Hi Bharath, it is done in the Bluetooth: Beacon sample.

[madhurubharath]

yes Hieu   thankyou for quick replay ,in Beacon sample code  they advertising constant  value but in my case it is sensor data it will change's  based on the temperature .

how to provide variable data into this code.

warm regards

because if i am trying to  provide a variable which increments continually it,s not taking  throwing error because BT_DATA_BYTE  multiline macro taking only constant values.
