PC SW connection to device throw BLE USB dongle

[jawadk]

Hi,

I am developing a PC SW that connects to nRF52840 device throw a BLE USB dongle(another nRF52840)

How I can tell from PC that a device is connected\disconnected to the dongle ?

Lets say in connection I can let the device send to PC a connection message, this way the PC can recognize a new device connected to the dongle.

But in disconnection situation this is a problem, since my dongle shall connect to more than one device.

How I can solve his ?

Another question:

what is the more accepted way to let the user chose from PC to what device to send the command to, sins more than one device connected to the dongle, what is the protocol !?

I will be glad if there is an example of it

That depends on what the two devices it is supposed to connect to are. Both should indeed work, so you should make your decision on what tasks you want the Dongle to do, as well as the connected devices. Based on the information you have already provided I'd suggest looking at using the Dongle as a central.

Best regards,
