BL651 "No idcode detected" Error

Hey,

I am a new to BLE devices. I am using BL651 Laird Connectivity's 453-00005 module

and using standalone JLink OB ARM debugger to connect.

When I try to connect my device with Segger Embedded Studio. It gives me an error.

"No idcode detected".

Also, I tried to connect it with JLink Commander v6.50 

In that, I am getting an error like

***************************************************

Connecting to target via SWD
InitTarget() start
InitTarget() end


Found SW-DP with ID 0x2BA01477
Failed to power up DAP


InitTarget() start
InitTarget() end


InitTarget() start
InitTarget() end


InitTarget() start
InitTarget() end

                               
Cannot connect to target.                          

***************************************************

For the first run I successfully connected with the device but then I got these errors.

I couldn't find any proper suggestions for this problem. 

Is there any suggestions to this problem?

Is there any chance that I might burn the device while I am soldering it. Because, I have other same module which works fine

Also the device may bricked itself, if so, how do i unlock it.

Regards,

Kemal
