central and peripheral nrf52840

[karthikeyan]

hi, i am having a doubt. now my nrf 52840 is acting as a peripheral. it is advertising some packets and my mobile is acting as a central and receiving the advertising packets. after the connection is made i want to edit some values in my mobile app and want to send it to my dk. for example i want to edit my tx power through app. which example will be suitable for this.

Hi Karthikeyan!

What kind of mobile app are you using?

I would suggest that you take a look at the ble_app_uart example.
That should help you acheive excactly what you want.

If you have any more questions, be sure to let me know.
Best regards,
Joakim.

hi joakim thanks for your reply. now i can see the value of my tx power, rssi, major minor, uuid and battery percentage through nrf connect app. our team is creating the mobile app in which we can edit tx power, major and minor, uuid values. after the editing these values my dk should get it and save it until i edit those values again. i had combined ble_app_uart and ble_app_proximity example and made some changes as per my need. but i am little bit confused to get the values from mobile app and save it. because my dk is now working as a peripheral. which example will be suitable for my needs.

I see.
Do you want the values that you provide in the mobile app to be added to the advertisement packet when received? And then have the peripheral advertise those values until changed again?
Best regards.

yes you are correct joakim. is there any example for this or i want to code by myself

[Joakim Jakobsen]

I'm afraid I don't know of any examples provided by us that does exactly this. So I guess you have to write the code yourself.
But if you face any problems you are welcome to ask for help here on DevZone.
