I’ve already spent a lot of time digging into the issue but no luck, so I have to ask for help.
I have an nRF51822-based device (sort of this one, it has 256/16 memory configuration, IC rev. 2) and I try to import and launch a common Central Test program (with or w/o libraries updated) on it. It flashes well, is able to connect to BLE peripheral devices, parse their advert data, etc., but when it comes to launchServiceDiscovery the sad story begins - only service discovery callbacks get called, but I’ve never seen any characteristics discovered. So, the question is - what can be done? Do I have to specify/change connection or scanning params (or else) to fix it?
