While scanning the FC41D Documents, I noticed that some pins have 4 antenna pins as alternative pins. In the description it says AoA/AoD (angle of arrival)/(angle of departure). So it looks like it can work as an Indoor Position Detection system. Is there a ready-made case study that can be shared with us about indoor location with BLE 5.0+?
Sorry, there are currently no relevant cases
Which IC is used for BLE in FC41D module?
The IC of FC41D is BK7231
