My project needs one dongle to link slave BT device and PC,but the distance is only less than 1m.
The hardware is :PC<>FTDI's usb to uart <>DA14580.The antenna I use is a ceramic antenna.
The software refer to the host project of DSPS_3.150.2.
At the beginning,I think the antenna doesn't match, I set the dongle as a slave device ,then communicate to the phone ,the distance is more than 10m,so I can ensure the antenna is good.
Well,I think the code should be changed,but I do not know.
Besides,Is DA14580 suitable for dongle?
This bothes me two weeks.
