I suggest you to use simple_peripheral for cc2650em example but remember to replace CC2650DK_7ID with CC2650DK_5XD in Predefined Symbols. You might also need to change GPIO pins for LEDs/BTNs according to your custom board.

I don't have CC2650DK_5XD. I do similar test on my CC2650DK_4XS and it works fine.
