Implementing PTT function via CC85XX

Shahab Qoli

Hi to all,

I want to implement Wireless adapter for radio handset like Motorola, and for this I must send PTT function via air to central unit, after reading CC85XX documents I cannot find some way  to do it via HCI and I think I must use external mcu for this, so if you have another idea please tell me our if I can program CC85XX by myself or add some small code in internal flash.

    Hi Shahab, 

    Depending on how this is solved in the central unit then you could solve this in autonomous mode. A slave can tie one of it's GIO pins to a button and the status of this GIO can be output on a master GIO or if the master is host controlled this status can be read over the SPI interface. This is done under 'remote control' in the User Interface panel of the PurePath Wireless Configurator. If both sides of the link are autonomous devices you can easily disregard the command names. 

    You can not add this in internal flash in other ways.

    Please let me know if the above solves your issue.

    Best regards,

    Hi Kjetil,

    Thanks for your answer and I think we can solve our project by this idea, another choose is CSR chipset like bluecore5 MM that they have internal flash and you can add some program on it. However I think we can use TI PurePath but I must add some component to add PTT function on Master side.

    Thanks
