Changing the bootloader advertising UUID

[inderveer]

Hi,

I am using NRF SDK 16.0.0 for device running on NRF52833 with softdevice version s140. The bootloader app advertises the DFU service uuid in the advertisement packet which is 0xFE59. I have tried to change the advertising UUID in the m_enc_advdata structure in the advertising_init() function in nrf_dfu_ble.c but this is not working. Still bootloader advertises with 0xFE59 uuid.

Is it possible to change this data for bootloader advertising packets? We need this because we have two separate devices, and both are advertising same uuid when in bootloader. If we can make one device advertise different uuid then it can help us differentiate between these two devices.

Regards,

Inderveer

Hi!

You could differentiate them based on the Advertising name instead.

In the bootloader project's sdk_config.h file, set NRF_DFU_BLE_ADV_NAME to a different name
