LPSTK-CC1352R: How do I find out the effective data rate for TI 15.4 sensor collector example?

Part Number: LPSTK-CC1352R
Other Parts Discussed in Thread: UNIFLASH

Hi,
I am running the TI 15.4 example on a CC1352 launchpad and the sensor example on the LPSTK-CC1352R. I want to find out how the effective data rate changes with changing distance in real world scenarios. How can I do that? I also saw that people calculate the packet error rate (PER) for this. Am I correct in assuming this? I could also not figure out how I can view the PER. The SimpleLink documentation about the sensor example says to "simply define DISPLAY_PER_STATS". But I couldn't understand where and how to define this.
Please help! I am a complete noob in this.

Hi Sidharth,

Data rate is fixed based on PHY selected, please refer to the TI 15.4-Stack -> Data-Rate and PHY section of the User's Guide: https://dev.ti.com/tirex/explore/node?a=pTTHBmu__&node=APeHcG.A0wniaym22zAYKw__pTTHBmu__LATEST

I recommend you get the collector/sensor examples working first with the SLA: https://dev.ti.com/tirex/explore/node?a=pTTHBmu__&node=AFU6dryAU8NukjdRPy4T4Q__pTTHBmu__LATEST

Once you've successfully used the UI please update the sensor project by replacing -DxDISPLAY_PER_STATS with -DDISPLAY_PER_STATS in sensor.opts

Regards,
Ryan

Hi Ryan,

Thanks for your response. I got the collector/sensor examples working and after then I tried replacing -DxDISPLAY_PER_STATS with -DDISPLAY_PER_STATS in sensor.opts as you had suggested. The sensor project was built successfully and uploaded successfully to the LPSTK. But on the sensor terminal I still see the same things as was displayed before making these changes:
Status: Rejoined--Mode=FH, Addr=0x0002, PanId=0x0001, Ch=FH

How do I see the PER? I am missing something?

Hi Sidharth,

Clean and rebuild the project, also completely erase device memory to clear out the NV items. If this does not work then debug SENSOR_UPDATE_STATS_EVT to understand what is happening inside Ssf_displayPerStats.

Ryan

Hi Ryan,

I erased the device memory using Uniflash and then cleaned and rebuilt the sensor project. It worked! Thanks for your help.
