want to know how can i judge that the variation is caused in the connection interval, connection supervision timeout, slave latency once i have flashed ble_app_template code in nrf52832 s132.

Hello,
The best way to see exactly how your connection parameter configuration affects the connection would be to use the nRF Sniffer tool to see exactly what is happening on-air.
Alternatively, if you just would like to play around with different connection parameters to see how each of them affects your connection you could take a look at the experimental ATT MTU throughput example from the SDK.
If you would like to visualize different connection parameter configurations you could take a look at the Online Power Profiler, which will let you see the effects of each configuration on the packet exchanges (as well as estimated power consumption).
Best regards,
Karl
Karl i am finding a difficulty in normal understanding the connection interval thing. Actually, by definition of CI i found it is the time btw two consecutive events for which the radio is turned ON. how can i judge this in nrf connect app?
Thanks for providing the logs.
Please also address the rest of my questions from my previous comments.
Best regards,
Karl
This looks like a screenshot of a single, random packet.
Please elaborate thoroughly on what you are trying to communicate.
Best regards,
Karl
karl what is the problem i am getting is that as i set 7.5-100ms i am able to get multiple logs but when i set to 1000-1000ms i get only 16 logs and after that my device stops logging

I know this already, you have said this before, but it seems that you might be ignoring my comments about the sniffer trace and debug session.
Could you share the whole sniffer trace with me here, so I may take a look? Please provide the trace for both the working and the non-working scenario.
Have you used a debug session to verify whether the program counter is getting stuck anywhere in the 16 log cases?
I have theorized before that it might be due to a buffer overflow or buildup when you change the connection interval to 1000 ms, since the buffers will be emptied much more infrequently with this connection interval.
Furthermore, what I asked in my previous comment was; what did you try to communicate with the screenshot of the single packet? What was it that you would like me to take a look at in this packet?
Please elaborate on your issues, address my questions, and be as specific as possible - so that we together may resolve your issues more quickly.
Best regards,
Karl

for sniffer trace i have a csv file how to share it?
You could share it using the Insert -> Image/Video/file option. Please also address my other questions.
Please share the .pcapng file, as generated by Wireshark.

Hello Karl,
My code works as:
press button
device advertise with name BTLog
Then i connect on nrf connect app on mobile
i press a button and put device in data logging mode with flash storage and temperature sensor interfaced
then after logging i press button again to make the device sleep
then again press button to readvertise
the from the service created i get the logged data using notification
i face issue in setting connection parameters :
i found that increasing CI reduces power consumption but
1st is for 7.5-100ms connection interval which accounts for more than 20 logs
2nd is for 1000-1000ms connection interval which only 4 logs after which i dont get logs
i am sharing you the wireshark traces:

Karl Ylvisaker pls administer the above issue
Hello again,
Please note that we do not provide support in the forum during the weekend.
Ridhi said:i found that increasing CI reduces power consumption but
This is correct, because it will lead to much more infrequent use of the RADIO peripheral, which in turn saves power.
Ridhi said:i am sharing you the wireshark traces:
Thank you for providing the traces. I do not immediately see anything abnormal in the traces - the connections are terminated by either the peripheral or the central in either cases, with no error. Everything seems nominal.
This makes me suspect that it is a application layer logical issue that is causing this. What could cause either the peripheral or the central to terminate the connection? Are they both programmed to terminate the connection when certain conditions are met, such as no data being sent for a specific period, or similar?
Both instances have a period of empty packets leading up to the connection termination.
Best regards,
Karl
