Modifying BLE Profiles for Simultaneous Data Transfer in Sensor Applications

Hi Pallavi,

It is possible to use normal Bluetooth services (standard or custom as you like) with normal connections side by side with Audio. We don't have any offical examples on that, but a colleague of me added a the NUS service to a ISO gateway here, which you can refer to as an example (note that this is for SDK 2.3.0 but the principles remain the same).

Hi Einar Thorsrud

I want to stream sensor data, over ble, while I hear an audio clip over ble (full-duplex), i.e. similar to calling someone for example, using ble to receive and transmit voice at the same time.

Any profile exists that will allow to do so, also is there any pre-existing profiles that will fit my requirements as described above?

If not, any guidance to achieve this.

TIA,
Pallavi

Hi,

A Bluetooth profile is essnetially a set of services, typically with one or more requiered and zero or more optional. You are free to add one or more services as you see fit. I would need to know more about what you are doing and what you need help with in order to provide more specific advice.
