nrf master tool cant display list of my personnal services after programming the bootlader region

[makouda]

after programming the bootlader region, I no longer see the list of my services ith nrf master tool. all what I can see is general attribut general access and device firmware update service

The bootloader will always be executed before the application when programmed (MBR reset behavior), but it won't "jump" to the application before it knows that there is an valid application present. See question 'E' in this FAQ for more details.

It's actually the bootlaoder that it's advertising its DFU service if I'm not mistaken. Try setting the app valid flag in the bootloader using nrfjprog:

nrfjprog --memwr 0x3FC00 --val 1
nrfjprog -r

Then check the ATT table again.
