BLE - NRF51 RADIO, using TIFS with DEVMATCH

[Andrew Lovelock]

Hi,

I want the NRF51 to respond to a received packet from a particular device using register TIFS to control the interfame timing.

For TIFS to work I have to set the DISABLED_TXEN short, but this will force a response to any device.

Do the DEVMISS / DEVMATCH events occur in time to abort the TX?

That is, can I use these events to either clear or set the DISABLE-TXEN short before the RX DISABLE event happens?

Or is there a better soultion?

Thanks Andrew

I'm having a little trouble understanding what you want. TIFS is not meant to be adjusted while using the radio, and you can not change it after having triggered the START task.

However, if you only want to respond to certain devices, can't you just make sure that these are the only devices in your RXADDRESSES? In that way, you shouldn't get any event at all for devices that are not wanted.
