CC8530 Questions

Other Parts Discussed in Thread: CC8530

Hello TI Engineering staff,

I'm working on a project with a group that creates a system of wireless headphones which can stream music between each other. The CC8530 IC seems to meet a lot of the basic requirements for the functioning of this system, but I've been looking through the datasheets and I am confused about a couple of things.

First, is it possible to use a single CC8530 chip that can be reprogrammed at the push of a button from the user to serve as the Master (Tx User who broadcasts whatever music they are listening to) or as the Slave (Rx which tries to acquire signals from a Tx user)?

Basically, can we switch from Receiving to Transmitting solely through a user interface?

Secondly, as far as I know the CC8530 does not contain an antenna, only the RF_P, and RF_N pin inputs from an external antenna. Is this correct? Also would the chip work with a half-wave dipole antenna connected?

  • Hi. 

    A device in the network can be configured/flashed to be either a master or a slave. You can not change role on the fly during operation. 

    That being said, wireless audio channels can be configured to go from master to slave or slave to master. If set up correctly you can achieve the functionality you describe between two headphones but not more. 

    CC8530 does not contain a antenna. Chip would work with a half-wave dipole as long as it is matched properly to the CC85xx device. There are multiple reference designs on www.ti.com you can follow and copy.
