Hey Jonathan,

Thanks for getting back to me.
But after further testing, it doesn't seem like a problem caused by the nordic device.
I'm currently looking into the implementation of the web browsers to figure the problem out.
Sorry about taking up your time.

regards,
Sethu

Hi Sethu,

Nothing obvious from the sniffer, can you explain more what you intend to do and what is not working after the " <wrn> bt_l2cap: Ignoring data for unknown channel ID 0x003a." shows up.

[quote user=""]This message shows up and the program does not progress any further.[/quote]

What do you expect to happen, where does it stop? What does not work.

If you are trying to enable notifications and nothing happens then you can check the code on the nRF device. See if it is in fact sending notifications or if it try's and fails. What gets returned?

Print what bt_hrs_notify(heartrate); returns to the log, what does it show?

Regards,
Jonathan

Hey,

Thanks for getting back to me.
Please find attached the sniffer trace capture file.
My initial thought was that the MTU size was too big, but it seems to be fine with it.
So, not really sure what's going wrong.
