RE: Multi-Link Peripheral - what is really needed?

Hi,

[quote user=""]Is there a guide somewhere which explains and illustrates what, exactly, needs to be changed to update a single-connection example to support multiple connections ?[/quote]

Unfortunately, we don't have the tutorial as your requirement. However, If you compare the BLE Multiperipheral Application and BLE Blinky Application these two examples, you will see the main work is maintaining links in the connection handle.

[quote user=""]In particular, I want to know: Apart from counting connections & re-starting advertising, is it necessary to do anything more at all in a Peripheral which has only Read & Write characteristics - no Notifications?[/quote]

The BLE Multiperipheral Application shows how one Peripheral can connect to several Centrals. To demonstrate this, program the example on one device to test several peripheral connections from this single device to several Centrals. You don't need to do anything for the characteristics even your peripheral application.

Hi,

I can just confirm that it works - without any further changes - at least if you can live with sudden disconnects after a few hours with "timeout" or "instant passed" HCI status. Also I didn't investigate how peer manager handles corner cases like simultaneous pairing from two masters (we're using our own peer manager).
