AMBE GPIO board #analog_bridge

Thank you for the great work of DVSwitch. I am trying to hook up my AMBE GPIO board which was made in Japan and similar to DV3000 GPIO board. It was working ok for AMBE server on RPI3B+ with the following setup: device port : /dev/ttyAMA0 baudrate : 460800
It doesn't work for DVSwitch with the following setup(s) in Analog_Bridge.ini: device port : /dev/ttyAMA0 baudrate : 460800 or 230400 (AMBEtest4.py showed this baudrate) serial : true
Interestingly, I get the different baudrate from the AMBEtest4.py on RPI3B+ Here is the result:
Setting serial port Serial port parameters: Port name: /dev/ttyAMA0 Baudrate: 230400 Byte size: 8 Parity: N Stop bits: 1 Xon Xoff: False RTS/CTS: False DST/DTR: False ********************* Silent testing mode..... Error, AMBE header was corrupt Error, no reply from DV3000. Command issued was: Reset DV3000 Error, AMBE header was corrupt Error, no reply from DV3000. Command issued was: Get Product ID Error, AMBE header was corrupt Error, no reply from DV3000. Command issued was: Get Version Error, AMBE header was corrupt Error, no reply from DV3000. Command issued was: Set DSTAR Mode Error, AMBE header was corrupt Error, no reply from DV3000. Command issued was: Reset DV3000 Error, AMBE header was corrupt Error, no reply from DV3000. Command issued was: Set DMR Mode Error, AMBE header was corrupt Error, no reply from DV3000. Command issued was: Decode AMBE Error, decode AMBE to PCM return no results Error, AMBE header was corrupt .......... ..........
Questions: 1. Does DVSwitch only support USB serial device ?
2. If it supports GPIO serial, is there other way of setup for GPIO device on Analog_Bridge.ini ?

Joe,

Analog_Bridge does support a Pi-Hat type of DV3000. Both Mike and a regularly run the NWDigital Pi-Hat DV3000. What parameter are you using to run AMBEtest4.py? It should be AMBEtest4.py --error --verbose -n --serial /dev/ttyAMA0 73, Steve N4IRS

Steve,
I didn't know about parameter very well for AMBEtest4.py. The result was without parameter. This time I tried with "AMBEtest4.py -e -v -n" and the baudrate was 460800 but it still doesn't seem to be properly working.
Port name: /dev/ttyAMA0
Baudrate: 460800 Byte size: 8 Parity: N Stop bits: 1 Xon Xoff: False RTS/CTS: False DST/DTR: False ********************* Testing Reset DV3000 Error, AMBE header was corrupt I found a thread which has something to do with the error message "AMBE header was corrupt" and I read KI7SBI solved his issue with a bigger power supply. I don't fully understand the main issue of his but I just tried with a couple of other big enough power supplies but no luck, meaning same return from AMBEtest4.py and the audio crashes on Dstar.
Any other suggestions?
p.s. When I set for a separate AMBE server with the proper address and port on Analog_Bridge.ini it works ok and the audio is very good.
