Other Parts Discussed in Thread: CC2541

Hi,

My requirement is to work  CC2541 Board in Dual Mode as Peripheral+Broadcaster.But it is not working.I have enabled PLUS_BROADCASTER in compile options in SimpleBLEPeripheral Project. While in a connection it is not broadcasting.

Can anyone please tell me whether BLE 1.4 stack supports Dual Mode.If so, please help me to do this.

Thanks.

Regards,

Anuhya.

    Hi Anuhya,
    You do not need the PLUS_BROADCASTER define, it's from legacy stack versions (the peripheral.c version that gets compiled in with this define is actually broken). You should be able to just start advertise once in a connection to broadcast information, with the SimpleBLEPeripleral as is.

    Best Regards

    HI,
    I am able to broadcast even while CC2541 peripheral is in connection.I have used SimpleBLEPeripheral project to do this as suggested above.But I have a small issue with that.
    The advertising interval defined as 160(i.e., 100msec).In non-connected state it is broadcasting for every 100msec, but while in a connection it is broadcasting for every 1sec. I have checked this using RF packet sniffer.How to change the broadcasting interval to 100msec even while in a connection.Please help me to solve this.

    Thanks.

    Regards,
    Anuhya.
