Custom service discovery on iOS

Documentation regarding bonding is spread out in the Bluetooth Core specification (and Devzone), I suggest you try to read about it there, and add a question if anything is unclear. These MSC's may also be useful. When you bond the GATT client can cache the attribute information, this is what you experienced before you removed the bond. Attribute Caching is described in Vol 3, Part G, Section 2.5.2 in the Bluetooth Core specification v4.2.

OK, I retried the custom example today with Master Control Panel, it worked. The time that didn't work is that I was not using Master Control Panel.

My custom service did work after I remove the bound in the settings. That makes me curious about How bonding works? How about the authentication? Is there any documentation that I could read about?

Thanks.

Thanks. These are very good example. I solved my problem by removing the bond in iOS' setting.

Many custom service examples from this Blog. All examples are updated to SDK 8. Blinky_be example : Control all gpio pins on the nRF51. Uart example : Bi directional using single characteristic. LMXDisplay_ble : Send text message to a LED matrix multi-display.

Are you sure you don't want to find out why the code from GitHub didn't work? If you are, please add a new question explaining what didn't work.

Anyways, the content of the advertising packet doesn't determine what services that are included in the GATT server, but it can advertise none, some, or all, of the services you have included in your GATT server.

You can see what services that are added to the GATT server by examining services_init() in the main loop of ble_app_proximity, so you can get rid of them there. Since you do not know how to get rid of them, I suspect you have not added your proprietary service correctly. But you say that you got everything working in Master Control Panel, so maybe my suspicion is incorrect. If it is, maybe this is something to do with bonding? Have you tried to forget device under Bluetooth settings?

Can you please edit your question to include how you ported your proprietary service into ble_app_proximity?
