@crispyoz I got it. Thanks a lot. I was just too excited

Ok, installed it again and it won't work.
I haven't use the omega for anything else before. I basically initialised it, installed mc and ogps and it's all.

When I install ogps and then use screen to read it I'm getting junk but as I wrote before, I assume it's normal.

The log file doesn't contains anything about "gps" whatsoever.

@Lazar-Demin @Marko-Lukat is there a way to change the baudrate?

Nope. It doesn't work with ttyS1 either. This is really weird.

@György-Farkas said in Enable UART2. Or use UART0:

picocom -b 9600 /dev/ttyS2

Ok, I followed your advice and it seems to be working. At least between my Mac and Omega.
I am not getting why I cannot communicate with the A9G from Omega when it works from my Mac.

It's weird

Connected A9G modem to it and tried to communicate with it. As it didn't worked connected it to a USB/TTL adapter and tried to establish connection between my Mac and Omega2

@György-Farkas said in How can I pass one GPIO pin to an other?:

Please...

Sorry about that

What is your Omega2 device?

Omega2+

What firmware are you using?

Device Firmware Version: 0.3.2 b232

Are you using an genuine Onion Dock?

How do you connect your A9Gboard to your Omega2? Some circuit diagram / schematic would be nice.

I'm not quite how does actually matters for my question but here you go

UART1 is connected to UART_GPS
Pin 16 and 17 (UART2) is connected AT_RX and AT_TX respectively. The UART2 doesn't work by the way.

I executed this command:

@György-Farkas said in enable uart2 is posiible on Omega2+??:

After this command omega2-ctrl gpiomux set spi_s pwm01_uart2 Omega2(+)'s UART2 (ttyS2) works well using GPIO16 as TX2 and GPIO17 as RX2 (8N1 default BAUD rate 9600 bps).

# Omega2+ FW v0.2.2 b201

set gpiomux spi_s -> pwm01_uart2

As the UART0 seems to be occupied by the operating system I tried to enable UART2 and followed this post but it just doesn't works for me.

Is there anything I might be missing?

Hi guys,

Thanks for your answers. Yes, this is what I actually tried to ask: how can i programmatically pass GND to those two pins.
I don't think connecting pins from Omega would do the trick as I need to pass GND.
For the moment the only idea I have is to buy relays but I would rather try to avoid it of possible

Regards,
Radek

Ha, ok

The one I use is a A9G. Sadly there is basically no documentation for this board.

Thanks in advance

Hi,

I'm probably thinking too much around so I will rather explain what I need.
I have a GPS tracker which has two pins, one for reset one for power on. Both needs a GND connected to these pins respectively for about three seconds.
Is it Possible to pass GND to those pins programmatically or do I need a relay for it

Radek
