Hi, I need to do the same with nRF8001. Within GAP settings, I would set "Service Data" in "Selected fields to advertise" (ACI Bond for example), create characteristic with property "Set pipe" then use "SetLocalData" to modify the data but how do I specify this characteristic to be the "Service data" to be advertised ? I can't understand how advertisement packet bits "uuid lsb" and "uuid msb" have to be set/used... I finally wrote a question, see "Service data in advertisement packets"

Nikita,

I am trying to change advertising when it is advertising using UART i.e., if I type anything on UART it should change the advertising data as coded by me. I have modifiedg ble_app_uart_s130_pca10028 example for this application to work. But its not working. Please help!!!

What is the difference here than calling advertising_init() and advertising_start() again, each time you want to change the adv packet?

Hi, When I'm trying to call ble_advdata_set(&advdata,&scanrsp) after a radio signal notification, the function return an invalid parameters error... Do you have any exemple to use sd_ble_gap_adv_data_set(), or ble_advdata_set() ? Thanks,

It's trouble with this forum, it adds < /p> at the end of the link if you write it at the end of message. Try this one: http://pastebin.com/E7KCCghB -

No, you don't need to call sd_ble_gap_adv_data_set yourself, it'll be callied inside ble_advdata_set(). And don't call ble_advdata_set() two times, one at the end is enough. Like this: http://pastebin.com/E7KCCghB

Sorry, I misunderstood your comment and though you resolve this question. See this for example of how to setup radio notifications devzone.nordicsemi.com/.../ So in ble_on_radio_active_evt() function if (radio_active == true) you need to call ble_advdata_set() with new advertising data.

Thanks nikitha ! i couldnt find the radio notification event () funtion !!! Am using the proximity example.now am trying to add scanresponse data as two numbers .Now during advertising those number should increment .It should increment on each advertising event .I displayed the scanned data but i couldnt update the values .The ble_advdata_set() is already called once by default in advertising init . but i dint understand where to use it again !

Well, for example, if you advertising only when you don't connected to any peer, then you can update advertising data with ble_advdata_set() call on radio notification event before advertising event: devzone.nordicsemi.com/.../a00913.html

You need to call ble_advdata_set() with all parameters needed every time you want to update your advertising data.

could you please explain how to use ble_advdata_set() inorder to update my data on each advertising event . the advertising_init() already have ble_advdata_set() func !!!! but it is not updating my value

I tried to use either but no luck, do you need to stop advertising -> change the data using ble_advdata_set -> start advertising again? The way I did was to expose ble_advdata_set in my while loop but again I did not see any data updated?

Thanks again for your help Ole! Much easier than expected.

You can change advertising data at any time, using sd_ble_gap_adv_data_set(), or as exposed through the ble_advdata module of the SDK, ble_advdata_set().
