Forscan Lite Android and CH340 chip

Post by joobloo » Fri Oct 25, 2019 8:20 pm

Just bought a VeePeak adapter from Amazon. Works fine in Windows, but in the Android app it is very laggy. I'm using the USB Universal driver. The Forscan Lite manual mentions a CH34X USB driver, but it's not in my app (which is the demo version). Was that driver removed? Should I return the VeePeak adapter and get one with an FTDI chip? Here is the adapter I have:

And here is what it says in the Forscan Lite manual:

- USB FTDI - connection using FTDI native driver, works only for FTDI USB-RS232 integral circuits. Cheap clones often use counterfeit circuits that are blocked in native drivers. In such cases USB Universal has to be used
- USB CH34X - connection using WCH native driver, works only for WCH CH34X
- USB Prolific 38400, 115200, 9600 - connection using FTDI native driver, works only for Prolific integral circuits. It blocks counterfeit integral circuits similar to FTDI. This driver can only use only a certain baud rates, this is why the list contains 3 USB Prolific connection types with 3 baud rates.
