Changing Characteristics and Services for BLE

userHead parporn1 2016-06-16 15:21:28 3522 Views3 Replies

I am modifying the source code for an iOS app (with Xcode) that connects to sensors via BLE. The app searches for a peripheral with a specific set of services and characteristics. How do I change the services and characteristics of my Bluno Beetle (version 1.93) from the default ones? I used the app LightBlue to see that there are currently 2 characteristics on the Bluno Beetle, with UUIDs DFB1 and DFB2- both of these can read, write, and notify. My current service UUID is DFB0. I would like to customize these so that I can connect the Beetle to the app.

This is my first time working with BLE and iOS app development, so any help would be appreciated.

Do you mean these 12 pins?

If so, yes, you can do it by the CC debugger, i bet you know it, lol :D

Actually, we have the guide how to do that here. ... service%3F (could be found in Bluno FAQ, Q5)

I noticed that on the Beetle board, there are 12 small pins on the back of it, possibly a way to reprogram the Bluetooth chip. Someone in my lab suggested that I look into this. Would it be possible to connect to the CC2540 chip on the board? If so, how would I go about doing it? If not, then would a way to do this be released in an updated version of the firmware?

Welcome to DFRobot and good day,

It happens that someone talked it, a similar question, these days. viewtopic.php?f=18&t=2035#p9213 Unfortunately, the UUID, DFB* are not allowed to modify, we did this in our code is to use the app to work with DFRobot BLE cards... (personally, I think this is not so good... :? )

Anyway, very glad to hear from you, welcome more questions and shares. :)
