Hi Anatya,

What kind of 6LoWPAN module are you talking about here. A specific TI design?

Hi Anatya,

1. Yes, CC1312R supports FHSS.

2. Yes, It is possible to change the frequency bands/number of channels as shown in the following application report

http://www.ti.com/lit/an/tida026/tida026.pdf

3. If you are referring to frequency hopping dwell time, it’s configured in CONFIG_DWELL_TIME (=250ms)

hanks Prasanna , Severin for your response. The customer has one follow-up query -

If the average signal level is above the signal threshold, the polite device defers its transmission to a later time. The equipment shall not attempt re-transmission on the same operating frequency until a random interval has expired (multiple of the minimum deferral period)

the above text is from https://www.etsi.org/deliver/etsi_en/300200_300299/30022001/03.01.01_60/en_30022001v030101p.pdf

page number 55

we are in need of " The minimal Unit of Deferral Period " i request you to kindly provide this i.e Minimal Unit of Deferral Period.

The customer has shared the configuration files with us earlier, please let me know if i can share the same.

Hi Anatya,

The backoff unit time used for deferring transmission is 20us. The actual defer time will be dependent on the number of attempts made. The default exponent of random backoff slots for min and max are 3 and 5.
