DA14531 multiple connections

Hi, Dialog

I read some publuc documents.

Here issaying, CFG_MAX_CONNECTIONS is used for GAPcentral role applications.

But here(and example exists) said DA14531 is able to support up to 3 simultaneous connections to more than one centrals.

Where is the truth?

I want to connect multple peripheral devices from DA14531. Is it possible?

Device:
DA14531

Hi alechek,

Hi alechek,

Thanks for your question online and for your interest in our DA14531 solution. The SDK6 supports up to 3 Peripheral connections when the DA14531 is configured as GAP Central role. That’s why the user manual mentions that the CFG_MAX_CONNECTIONS macro should be used for GAP central role applications.

If you check theDA14585/DA14586 - DA14531 Multiperipheral ExampleSW example, you will see that a single peripheral can be connected to more than one centrals (up to 3 centrals for the DA14531). In order to achieve this, SDK modifications should be done. The Readme file includes those SDK modifications so that a single DA14531 peripheral can support up to 3 centrals connected.

Thanks, PM_Dialog
