RE: Unhandled exception in Master Control Panel 3.8.0.7

I have tried another application and this does not cause the unhandled exception. Also, I don't always see the error so something in my application seems to be triggering it. The exception occurs at the same time that the message "Received Connection Parameter Update Request" is shown in the log.

I have attached the hex file: Demo.hex

EDIT:

Ok I see. I can see how this is an unexpected value seen from the MCP's perspective (though it shouldn't of course cause an exception) but shouldn't the softdevice check for ou of range values and return an error code to my application?

I'm not able to reproduce the error just by using a standard SDK example. Anyway, I don't think MCP should give you an unhandled execption error, so it could be a bug. Maybe you can post the hex-file of the application you created. Then I can test it out here.

EDIT

I tested the hex-file and I managed to reproduce the error. The Connection Parameter Update Request packet has a field called Timeout Multiplier. You set this field to 0xFFFF (=65535). In the BLE core specification 4.2 page 83 (Vol 3, Part A, section 4.20) you can read about this packet. The range of the timeout field is specified to be between 10 and 3200, which is below your value. So that's why MCP throws an exception.
