Update data of extended advertisement (BLE5)

[QuentinD]

Hello

I would like to use the extended advertisement feature of BLE 5 and sometimes update the data.

My code works but there is one of your functions which returns me an error code which disturbs a little.
When I call the "ble_advertising_advdata_update(...)" function, there is function "sd_ble_gap_adv_set_configure(...)" which returns error 9 (NRF_ERROR_INVALID_LENGTH).

I notice that if adv_data is smaller than 32 bytes, I have no error but if it is larger then I have error 9 ...

However I use the "extended" functionality so I should be able to exceed 31 bytes of adv_data right?

Hi Quentin

The following procedure should be sufficient. Stop advertising usingsd_ble_gap_adv_stop, run another advertising_init() function where you change your advertising parameters, and start again. Seeing as you apparently don't have enough memory to do so though, you should update the existing advertising handle. Please see the sd_ble_gap_adv_set_configure documentation on the Infocenter.

Best regards,

Simon

Hi

It works now.

For this to work, I had to do a ble_advertising_init (...) and then a ble_advertising_conn_cfg_tag_set (...)

Thank you
