Hi !

Is it possible to support 2 connections simultaneously as master and slave, with one connection in LE mode 1M Coded PHY, and another LE 1M?

    Hello,

    Yes this is possible both by our stack and the Bluetooth Spec, depending on your needs you may run into resource issues (i.e RAM and flash) on CC2640R2.

    A couple questions:

    1. Do you need to establish a connection in long range mode (Advertising Extension supported)?
    2. Do you need any other features of LE Extended Advertising?
    3. Are you okay with using an evaluation version of the Long Range mode PHY?

    If no, no, yes to above then I would recommend starting from multi_role in the CC2640R2 SDK 1.40.00.45 and establishing both connections using the 1M PHY and then use the HCI_setPhy command to switch to a long range PHY.
    Otherwise you might be interested in checking out CC2640R2 SDK 1.50.00.71 which supports advertising extension, but does not have a multi_role project available. (still evaluation mode)

    Lastly, for the optimal amount of resources and multi_role support out of the box I would use the CC26x2 SDK 1.60.00.43. (note this requires a CC26x2). www.ti.com/.../SIMPLELINK-CC26x2-SDK
