Your keyboard or it’s driver may be faulty and that is why it’s missing keystrokes.
But please be aware that the missing keystrokes may be caused by a multitude of communication problems between the keyboard and the V.
Singling the bluetooth driver as the ONLY possible cause of missed keystrokes is possible, but not likely.
Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2,4 to 2,485 GHz) from fixed and mobile devices, and building personal area networks (PANs).
Here are a few mentioned (do you have any of them?).
The following things can cause interference with Bluetooth devices, if they are nearby (don’t forget your neighbours):
- Using your microwave oven near your computer or Bluetooth device might cause interference.
Direct Satellite Service (DSS)
- The coaxial cable and connectors used with some types of satellite dishes can cause interference. Check the cabling for damage that could cause radio frequency interference (RF leakage). Try replacement cables, if you suspect interference.
- Certain external electrical sources like power lines, electrical railroad tracks, and power stations can cause interference.
2,4 GHz or 5 GHz phones
- A cordless telephone that operates in the 2,4 GHz or 5 GHz range can cause interference with wireless devices or networks while taking calls.
Wireless RF video
- Wireless video transmitters that operate in the 2,4 GHz or 5 GHz bandwidth can cause interference with wireless devices or networks.
- Wireless audio that operates in the 2,4 GHz or 5 GHz bandwidth can cause interference with other wireless devices or networks.
Certain external monitors and LCD displays
- Certain displays can emit harmonic interference, especially in the 2,4GHz band between channels 11 and 14. This interference might be stronger, if you’re using a notebook computer with the lid closed and have an external monitor connected. Try changing your access point to use 5 GHz or a lower 2,4 GHz channel.
Poorly shielded cabling
- External hard drives or other devices with poorly shielded cabling can interfere with your wireless devices. If disconnecting or turning off the device appears to help, try replacing the cable that connects the device to your computer.
Other wireless devices
- Other wireless devices that operate in the 2,4 GHz or 5 GHz bandwidth (microwave transmitters, wireless cameras, baby monitors, a neighbour’s WiFi device) can cause interference with bluetooth connections.
Obviously the possible causes for missed keystrokes don’t stop there. The keyboard could be mechanically faulty, does it miss certain keys?
Is the keyboard fully or nearly fully charged? Does charging the keyboard make a difference? Low battery charge could make bluetooth communication intermittent.
There are probably other potential causes for missed keystrokes, but these are the most common ones - faulty or corrupt driver included.
Usually the faulty/corrupt driver can be rectified by deleting and reinstalling the device and driver.
Please also try the keyboard in different environments and see if that makes a difference. There are radio transmissions and interference everywhere nowadays, but your usual environment may have a particular transmission or interference that hinders the keyboard’s normal function.
