change nrf51822 service flags

[Neshat]

Hey there, I have beacon device, its nrf51822 and it is a pretty standard beacon but it is not nrf beacon(so it does not have sw1 and sw2 buttons), when I search for it with beacon connect and i check services and flags, I see that LE limited discoverable mode flag is 0. how can change it to 1? can change it wirelessly? or i have to connect to nrfgo studio?

The adverting flag has to be changed in the code. To update the new firmware to your device you can either use the regular programming interface, or update the firmware over the air if you have added support for that.

how can I add support for over the air update in my firmware?

For how to implement a bootloader, I would recommend you to take a look at the bootloader(DFU) example and the bootloader documentation.
