Hi Mani,
   Thanks for this review. 
   Actually this product(SDX55/0xe0bf) is using Qualcomm SDX55 new baseline(LE1.4), 
 and previous T99W175/0xe0ab is using original base line(LE1.2).
   Our customer wants us to use different device ID to separate from each other. 
   Currently we don't have product page  as our customer's new product is not released.

Thanks
Slark
