Hi, i have issue on 10.11 (El Capitan), i can figure to which port is connected projector (its connected via thunderbolt port - i have thunderbolt -> vga cable). And i have question, will i be able to show with pyjector image or some text on the projector?

Hi I 'm trying to get your awesome project to work with my Benq MP626. But I bet this errors:

./pyjector_controller benq "/dev/ttyUSB0" power on
Traceback (most recent call last):
File "./pyjector_controller", line 18, in
pyjector = Pyjector(port=args.port, device_id=args.device)

ValueError: Expecting object: line 356 column 6 (char 9289)

I don't have that much experience with python. Du you know if I'm missing something?

I get the following error:

carsten@ubuntu:~/$ python3 pyjector_test.py

TypeError: must be str, not bytes

I use the following test script under python 3.6:

from pyjector.pyjector import Pyjector

# Look up what port your projector is connected to, using something
# like `dmesg` if you're on linux.
port = '/dev/ttyUSB0'

# The only valid device id at the moment is `benq`. This is used
# to figure out what commands are supported, and the format needed.
device_id = 'benq'

pyjector = Pyjector(port=port, device_id=device_id)

# Let's check what commands claim to be supported by our device.
#print(pyjector.command_list)

# Let's check the actions associated with each command
#print(pyjector.command_spec)

# Turn the projector on
#pyjector.power('on')
# We need to change the source, which are supported?
print(pyjector.get_actions_for_command('source'))
# Change the source to hdmi-2
pyjector.source('hdmi')

So unlike everybody else i dont have a USB Converter to go from USB to Serial Connection, im simply using the connector on the back of an old DELL laptop, (It has no other use to me currently)

It is loaded with Ubuntu Server 16.04 and has no outstanding issues to my knowledge, the Com Ports show up without any issues under dmesg as shown below:

root@DELL-COM-PORT:~/pyjector# dmesg | grep tty
[    0.000000] console [tty0] enabled
[    2.340164] 00:07: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
[    4.754379] tty tty20: hash matches

But when i try and send anything to the Projector i get this error:

Traceback (most recent call last):
  File "./pyjector_controller", line 21, in <module>
    command(args.action)
  File "/root/pyjector/pyjector/pyjector.py", line 298, in handler

  File "/root/pyjector/pyjector/pyjector.py", line 278, in _check_response
    response
pyjector.pyjector.CommandFailedError: ('Received an unknown response', u'')

The projector is a Optoma H183X too

Any help would be great!

The command for high altitude mode has a syntax error:

        "high_altitude_mode": {
            "command": "Highaltitude",
                "on": "on",
                "off": "off",
                "status": "?"
            }
        },

This is missing the line

            "actions": {

from what i have gathered my serial connection is established and minicom verifies that its talking (i think, like you said kind of a weird program to understand) and i can do the ./pyjector_controller benq "/dev/ttyUSB0" power on , the termianl pauses for a sec like its sending the command but the projector still stays off. Also have tried to turn it off from an "on" state , but no luck either. Any help would be greatly appeciated!

I'm building a config for my epson projector but I have an issue the commands for status are without a separator. For example:

PWR ON\r -> powers the projector on
PWR OFF\r -> powers the projector off
PWR?\r -> gets the status

There is no space between PWR and ?.

Have you had this problem previously?

./pyjector_controller -d benq "/dev/ttyAMA0" power on

When I inserted .encode('ascii') it started working.
