Reading the application version, bootloader version of a device connected through bluetooth.

[Vardhan Bhargava]

Hi,

I am using nrf52 DK board.

After uploading my bootloader and application on a device that is connected through bluetooth with my board, i want to know the application version and the bootloader version that has been uploaded. This is being done to check if the bootloader and Application that have been uploaded are correct or not.

I am writing a python program to read the Information from the device.

I think this uses the Device Information Service but i don't know how to use that. Need help.

Thank you!

Hi,

Yes, you can use the Device Information Service (API) for that. You need populate it with the correct version numbers when you initialize it, for example getting application and bootloader version from the bootoader settings in flash (nrf_dfu_settings_t). There is no standardized field for bootloader version, but you could perhaps use the FW revision for bootloader and SW revision for application.
