Hi,

I'm working with Non-Beacon Mode. What's the difference between

CONFIG_MAX_RETRIES and

CONFIG_MAX_DATA_FAILURES

for the device to enter orphan mode?

Thank you

Hi,

CONFIG_MAX_RETRIES determines the maximum number of retries (after a transmission failure) at the MAC layer for a single frame, after which the next higher layer is notified of the failure.

CONFIG_MAX_DATA_FAILURES determines how many application data requests (eg poll, sensor reports, etc) can fail before the sensor enters the orphan state (as handled by handleMaxDataFail() in jdllc.c).

Regards,
Toby

Thanks for your answer, Toby Pan.

So when we reach a number of failures equal to CONFIG_MAX_RETRIES, a variable counting data_failures increases by 1 until it reaches CONFIG_MAX_DATA_FAILURES; when this happens, the sensor assumes it is orphan.

Is this correct?

Yes.

Search CONFIG_MAX_DATA_FAILURES in the sensor's jdllc.c to check the code for this.
