Hi Bharath,

Both the beacon and ibeacon samples show how to use the Manufacturer Specific Data AD Type.

You can update data dynamically using this API: bt_le_adv_update_data().

i found example in "i beacon" sample code ,using manufacture data specific how to pass sensor data to advertise .in this array.

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.

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

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

tq hieu for correcting the wrong path ,

can you provide sample code ,how to advertise "manufacturer specific data" with out connecting to nrf52833 in nrf connect mobilw app.

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.
