Part Number: CC2640
Other Parts Discussed in Thread: CC2540,

Hello,

I download the python script for cc2540 from following link

I am using cc2540 dongle which is acting as host. On the other side i have cc2640 as peripheral. I am able to run the script and it is doing discovery of all devices near by. But when i try to connect some device it shows the connection interval of zero and timeout also zero.

following is the screenshot of output for connection establishment. Is there any configuration missing or something else? Please help to solve the problem.

Thanks a lot.

waiting for your kind reply.

Hi YiKai Chen,

Now it is showing incorrect values of these parameters:

Connection interval: 1930.0 msec
Connection latency: 0.0 msec
Connection timeout: 16000.0 msec

Can you tell me where is the issue?

I found the issue parsing of event data was wrong in original script.
