Hi,
Using windows 10 OS, and SES v5.40.
I am using nRF52833 device in my project along with nRF5_SDK_for_Thread_and Zigbee_v4.1.0_32ce5f8 SDK.
I am using openthread protocol and specifically otError otLinkSetPollPeriod( otInstance *aInstance, uint32_t aPollPeriod ) function to input the poll period.
Problem statement : the above said function is nothing but the communication poll period and i see from the documentation(https://openthread.io/reference/group/api-link-link) that it is a U32 variable which has max limit of 0x3FFFFFFF and min 10ms for its operation.
But if i run a test by inputting aPollPeriod to some higher value i can see that the value is somehow cutting down to 188s(approx. 3mins).
Ex : Test 1 : if i run with 60 sec(60000) as input i can see that the value of poll period is 60s(59999ms).
Ex : Test 2 : if i run with 200 sec(200000) as input i can see that the value of poll period is 188s(188676ms).
Ex : Test 2 : if i run with 350 sec(350000) as input i can see that the value of poll period is 188s(188676ms).
I am trying to test this with a inbuilt feature of our code that can measure the time and i have attached the debug information for further reference.
Questions:
1. what is the max value that can be input to this aPollPeriod (practically)?
2. Is 188s is the threshold for the pollperiod?
