Hi,
I am trying to get precise timings for Rx packets in order to synchronize multiple devices. I see in the documentation that the RAT_GPO1 (Sync word detected) is not available for the IEEE 802.15.4 :
9 | RAT_GPO1 | Goes high when sync word is detected and low either when the packet has been received or reception has been aborted. Not available for IEEE 802.15.4 RX commands. Requires an additional override (uint32_t)0x008F88B3 |
- Do you have any plans in the near future to enable this signal for the IEEE 802.15.4 standard ? The override wont work in 802.15.4 right ?
Is there any alternative to this missing signal ? I found that mdmsoft might be useful but I wonder :
- Is there any delay added when using a callback from the event RF_EventMdmSoft ? If so, is this delay consistently the same ?
- Is there a difference (in time) between RF_EventMdmSoft callback and the interrupt RFHWIFG.MDMSOFT, which is the most precise way to get the sync word detection
Best regards,
Clement
