If you are programming the BluChip Explorer kit with a J-Link device it may be necessary to power the BluChip with an external 3.3V source. The CR2032 voltage may drop below the allowable threshold for the J-Link. In Keil this will manifest itself with errors when trying to load or debug a program The IBDAP CMSIS-DAP programmer supplies power for the BluChip so this is not an issue when programming with that debugger.
