softdevice - Write custom BLE advertise with custom TYPE

[Neeraj Dhekale]

Hello,

I am using the nRF52840 DK board and with Softdevice code nRF SDK 17.0.2. I am trying to write custom advertise data with custom type.

As you can see in the above screenshot. Like 0x16 and 0x09 I want to set my data to some other type for example 0x06 or 0x07. How can implement this? Earlier I have done the same in Zephyr in the same nRF52840 successfully, but I am not sure how to do this in Softdevice. Please let me know how can do this?

so as you can see in screenshot 0x16 was written due to the below statement:

uint8_t test[2] = {0x07,0x02};
ble_advdata_service_data_t obj;
obj.service_uuid = BLE_UUID_TX_POWER_SERVICE;

obj.data.p_data = test;
obj.data.size = 2;

init.advdata.p_service_data_array =&obj;
    init.advdata.service_data_count=1;

Thanks and regards,

Hello,

For example I want to set BLE_GAP_AD_TYPE_128BIT_SERVICE_UUID_MORE_AVAILABLE or BLE_GAP_AD_TYPE_128BIT_SERVICE_UUID_COMPLETE.

Where I can set the above-defined instead of 0x16 (BLE_GAP_AD_TYPE_SERVICE_DATA)?

Hi Neeraj,

You can check out the ble_advdata module in the nRF5_SDK_17.1.0_ddde560\components\ble\common\ble_advdata.c

If you use this module, you can add the data to the corresponding member of the struct and the library will add the particular data type in the advertising packet.
