I am using a CYBLE-014008-00 and I am having an issue where the BLE connection will drop intermittently. This usually happens after 10-15 minutes of connection but sometimes sooner. Any suggestions on this would be very helpful.

The correct ECO frequency is critical to reliable BLE operation. The capacitor trims may need to be adjusted.

Have you seen this: https://community.infineon.com/t5/Knowledge-Base-Articles/ECO-Capacitance-Trim-Values-for-EZ-BLE-Mod...

Which tells you to use 0x9595 for the CYBLE-014008-00. I just discovered that those values are actually in the module datasheet (PDF). Just search for "ECOTRIM".

Personally, I don't have any faith in those numbers. There's a couple of current posts discussing verification of correct trim.
