All your questions are on BLE. As @AScha.3 said, maybe no one knows a useful answer?
Of all the companies I've worked at, there hasn't been a single project that used Bluetooth. So anyone asking a question on BLE specifically, I don't even look at the post. If it pertains to serial communication with a BLE module, then maybe. Could be the same for others and why you're not getting a reply?
So maybe you should move to Nordic Semiconductor as you said you were?
