CC3235SF: BLE coexistence PIN of GPIO0

LEON YAN

Part Number: CC3235SF

Hi e2e,

Our customer is using CC3235SF + BLE doing coexistence application, in CC3235SF datasheet and LP schematic, GPIO0 is used for coexistence, but in an application note, it doesn't mention the GPIO0 as coexistence function pin, what's the reason there?

and what's the different between CC_COEX_BLE and CC_COEX_WAKEUP in Launchpad design?

thanks in advance.

Leon,

GPIO0 is available for COEX. our datasheet is correct, and the app note needs to be updated to include it. For the CC_COEX_BLE and CC_COEX_WAKEUP pins, these pins are what the two devices use to communicate when it is Clear To Send there packets.

Best Regards,
Vince
