Is the nRF52832 fitted with Bluetooth multipairing?

Hello

I have a question about the Bluetooth multipairing function using nrf52832.
How do I use this feature? And up to how many connections can I make?

Thank you!

Hi,

By multipairing do you mean bonding to multiple devices? That is supported out of the box on most (if not all) the SDK examples that use bluetooth pairing. There is no upper limit on how many bonds the nRF can have, as lon gas the bonding information fits in flash. In practice this would be a very high number unless your device is flash constrained (see this post).

Regarding number of connections the maximum number of concurrent connections supported by the SoftDevice BLE stack is 20. You may not get as high in practice, as it depends on connection parameters and available memory. You can refer to Experimental: BLE Multiperipheral Application for an exmaple of a peripheral that can be concurrently connected to multiple centrals. The BLE Multi-link Example demonstrates a central that is connected to multiple peripherals.

Thank you, Einar!
I will refer to what you told me.
