CC2640: Peripheral connected to 2 centrals

Hi Pixbroker,

The Multirole example project supports multiple connections for Peripherals. I would recommend using the CC2640R2F and the latest SDK (1.35 at time of writing) as this will provide you a Multirole project included in the SDK.

Cheers,
Fredrik

Hi Pixbroker,

EDIT: Fredrik got to it before me! He's right, I'd go with the multirole configuration; note this will take up considerably more flash - you may want to consider doing this from host_test (which has it's own considerations, such as requiring knowledge of HCI commands, etc)

I personally haven't tried it - our peripheral gaprole (peripheral.c/.h) isn't exactly designed for it, making it more like the central role should allow you to do this. (ie instead of relying on one connection handle for everything)

My concern would be that the peripheral stack configuration might be missing some random stack code. (So do this in a multirole configuration if that's the case)

What's the use case for this?

Regards,
Rebel

Thanks Fredrik, sadly we are stuck with CC2640 hardware for the time being.

Does the multirole example work with BLE Stack 2.1? (2_01_00_44423)

Then you should update to 2.2.1 and get the project from here: github.com/.../ble_examples-2.2

Sadly we have some heap problems updating our project to 2.2, so we are stuck with 2.1 for now. Is multi-role (1 peripheral, connected to 2 centrals) not technically possible with 2.1?

We do have an example for 2.1 also, but there are several bugs in it and I would not recommend using it.
