Nordic Mesh SDK issue with a Nordic Module by Laird(BL652)


I have been working with Bluetooth Mesh SDK since few months. Recently, we came across a custom BLE module which has Laird's BL652(nRf52832) chip on it (Not the BL652 DK). We tried to execute few UART  examples on the module which worked fine. When we tried to flash the Mesh examples like light_switch server, enocean, etc. to control the module using the nRF Mesh App, the execution stops in the initialize function and start function in the main(). 

I am attaching the link of the BL652 by Laird for your reference here.

I can't even see any response on the debug terminal other than the name of the example. Any idea on how to resolve the issue?

Thank you.
