Bluetooth LE question for hearing aid pairing

[tech.stuff]

I am looking for a pairing between Windows laptop or Android mobile on the transmitter side and hearing aid which has bluetooth streaming features as a receiver..

I am looking to create this remote control assistant that will make the link between the hearing aids and the laptop/mobile. 

I am having trouble finding information on the principle of this creation. My assistant will have to be compatible with BLE Audio because this remote control is just used to connect the transmitter and receiver together which would allow to use another chip.

I wish to know whether nRF52840_DONGLE can be used for this purpose or not. Are there any custom low cost solutions that can be configured to test this out.

It sounds like you wish to create a Broadcast Assistant.

Another great source of information about LE audio in general is Nick Hunn's book

An example Assistant which may be run on Nordic devices may be found in samples/bluetooth/bap_broadcast_assistant

Although various devices may be used to implement this, be aware that it can become a bit complicated, as support for this feature is relatively recent and may depend on both manufacturer and device.
