CC2640R2F: Acces a characteristic without bonding/pairing

BRUNO CHAVES

Part Number: CC2640R2F
Other Parts Discussed in Thread: CC2640

I'm using cc2640 with HID_emu_kbd project. I'm using a mouse HID mouse descriptor on my device and I it is already working fine. One of my applications is to read a mouse characteristic value that we built to know mouse click, x and y position without using the HID protocol. In other words this specific central device will read the mouse values from outside of the hid report and I'm alson making it right. The problem is that I need to pair and make a bonding with the device to access the charactistic and I want to read it just by connecting because it is not very easy to make the pairing in this central device that I'm using. Is it possible to see the characterisitc values withou bonding?

Hi Bruno,

You don't necessary need a connection to obtain data, if your peripheral advertise data you can scan them from your central without connection. First I suggest you to have a look at our user's guide and more specifically at the Generic Attribute Profile (GATT) section to know more about it and secondly to follow the CC2640 labs we have, have a look at the Scanning and Advertising one.

Hope this help a little,

regards

Hi Bruno,

If you are using the hid_emu_kbd as base for your project you need to pair it to for example your laptop. What is the central device that has problems in pairing?

Hi, I'm using banana pi as central, it takes the mouse x,y and click values to control another electronic device. However, the first connection with the banana pi is too slow (almost 15 seconds), so I want to read the mouse values without the need of the pairing

Hi Bruno,

I have used the hid_emu_kbd to connect my project to laptop. I can't remember if the pairing is required for the mouse x,y and click to be detected. Can you try not pairing it to banana pi. I remember the pairing is for the auto connect.
