I have a raspberry Pi 4B 4GB ram and I want to connect it to 16 Bluetooth oximeters(BLE) and take readings after every 20 secs.
Now I know that pi can connect to only 7-8 Bluetooth devices at a time so Can I use 2 USB Bluetooth adapters to connect to over 15 oximeters ?
If yes, is it a good solution?
If no, what else can I use/do?
