CC1312R: Determine Packet Error Ratio

Dirk Uhlemann

Part Number: CC1312R

Hello,

In a measuring application (15.4 stack), I have to determine and transmit
the packet error ratio (per) frequently with the other sensor data.

How to do this?
Are there any Code examples?

Kind regards,
Dirk

ps
I use 2.40.00.81 SDK, with tiRTOS

I suppose you can use TI 15.4 Stack collector/sensor examples and setup sniffer to do PER test.

Hello YiKai,

I wont to determine and transmit the Packet Error Ratio in the field.
In my normal application should be a data field
that include the actual res-value.

Best Regards,
Dirk

Then, you have to implement application level transmitting acknowledgement mechanism to calculate PER in field and send it with your proprietary data field.

Hello YiKai,

Do You have a example Code for this or any
productive assistance for this problem?

Thanks,
Dirk

Sorry I don't have example codes for this and if you think my reply is not productive, I will keep silent from now on on this thread.

Hello Dirk,

Our SDK examples are able to calculate PER.

On the Sensor example from the SDK, predefine the following symbol: DISPLAY_PER_STATS

This should be enough for you to calculate PER over time. You can modify the code to your liking.

Also, each sensor sends over statistics about its connection on every packet (enabled by default) you can also use this information to do some PER measurements.

I hope this helps,
