You can start the GDB server with the command @Nabil posted, but you need to change the device from cortex-m4 to nrf51822.

Here are the commands I typically use to start a new debug session:

jlinkgdbservercl  -select USB -device nRF51 -if SWD -speed 4000 // starts server
arm-none-eabi-gdb *.out/*.elf // starts GDB session and loads debug symbols from input

//in GDB (may be added to .gdbinit)
target remote localhost:2331 // connects to server
mon reset 0 // reset target

That said, I would recommend to consider Segger Ozone as an alternative to GDB.

This command can active your remote server and allow you to debug with DDD :

 JLinkGDBServer -If SWD -Speed 4000 -Device Cortex-M4

Hello,

You can use JLinkGDBServer to make a link with your debug software ( like DDD on linux )
