Discovery problem on tlsr8251

Hi, I have a problem with a tlsr8251 as peripheral. When I use gatttool sofware on linux as central I have success on getting handlers from services and characteristics. We have the same solution with nrf51822(nordic device) as central and another nrf51822 as peripheral and the discovery works great. But when I try to use this same version of nrf51822 as central and try to connect with tlsr8251 as peripheral I can't receive any answer from discovery. One detail is that tlsr8251 as a central can't get a answer from tlsr8251 as peripheral too.

Hi, I'm sorry to hear that. I need to make sure which SDK and which build target you are using.

TLSR8251 central and peripheral should work well in my opinion. Maybe you need to enable SDP feature in your code. But I still need to know which SDK first. It means I need to know if it is Multi-conn SDK or Single-conn SDK, and which version.
