Dear Pros，
I use BLE Device Monitor software and bluetooth dongle to scan the bluetooth Device, but it is often impossible to scan the Device.In the same environment,
I can scan it with my phone and iPad. Have you ever solved this problem before? any suggestions to check？
1. Under normal circumstances, search 10 times or so will fail 1-2 times, under abnormal circumstances, search 10 times or so will be successful 1-2 times.
2. Currently, we want to use dongle to scan other bluetooth devices, but we have not established the connection yet, so we cannot scan it now.
3. Current changed the dongle of several manufacturer, have this kind of problem.TI official also has dongle, also used, the result is the same.
I have tried both near and far To test the effect of the rf antenna, with the same effect. Dongle's software program is the current official program,;
Any Suggestions？ many thanks；
