Tool/software: Code Composer Studio
Hey guys,
this is a follow up question from this https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/p/916245/3394707#3394707
I went through documentation and I additionally checked the settings in easylink_config.h. During certification, we want to use our final software, which mainly bases on the sensor/collector example from the 15.4 Stack, which includes CSMA-CA and LBT. I repost the the table from the EN 300 220 guideline:
According to our certification lab, we have to provide quantitative information (see Annex D, EN 300 220-2). So here my questions:
- Is the CCA interval in the sensor/collector example also 250µs, like it is in the easylink example? Or is it 2^3 * 250µs since CONFIG_MIN_BE = 3 ?
- What is the deferral period and to what value is it set in the sensor/collector example?
- What is the minimum unit of deferral period in our application?
- In the easylink example, the dead time is set to 5ms, which is the limit. Can and should we set this to something like 4.8 ms?
- What is the minimum Toff_min on the same operating frequency in the sensor collector example? How is this parameter controlled within sensor/collector example? Are message retries fired faster than 100 ms?!
Sorry for bothering you again, but we need this info for passing the tests.
best wishes
