CC2640 CCS example on using RF core API?

Hi YK Chen,

Thanks for your suggestion but I don't think that is what I wanted.

I am developing a production firmware that will put CC2640 radio to RX mode to constantly receiving RSSI value from DUT (TX continuously)and display it on an LCD display without the need of an external PC.

Any pointer from anyone?

Is it possible to use the CC26xx RF core HAL library via CCS?

Thanks.

This may help:

extern hciStatus_t HCI_ReadRssiCmd( uint16 connHandle );

browse hci.h and you should be able to find the commands you need to accomplish this.

Hi Ben,


Thanks for your great pointer.


If I run the receiver modem test which does not have any BLE connection, what should I put for "connect handle" parameter for the HCI_ReadRSSICmd() ?

I would give the value 0 a shot. I'm not sure off hand. Also you'll have to register your application task for HCI command complete events and get the returned info there. There is an example of this in SimpleBLECentral with the latest stack V2.1.
