Why does BlueSnap Standard sometimes drop characters when in HID mode?

This is an issue with the host device not handling keyboard input (this is how data is sent to the host device in Bluetooth HID mode) fast enough. This is always a risk when using Bluetooth HID, and this issue is known to exist on all iOS and Android HID devices.

Configuring the device attached to the BlueSnap Standard to send data at slower intervals could help resolve this. Alternatively, you can switch the Bluetooth SPP (if your application supports it) or switch the BlueSnap Smart and use Bluetooth Low Energy (BLE).
