Serial Bridge issue

Hi All, i’m trying to send to the surface pc a 232 string from a survey instrument connected to the com port 4 on the navigator. I’m sure the instrument is connected correctly and its sending the data as i can see the raw string on the terminal with the command “screen /dev/ttyAMA2 57600” .

THe problem occur when i try to create the serial bridge, set as server and then use the IP 0.0.0.0 with the port 15000. THe serial bridge extension isn’t giving any error and show the port is created but effectively i’m not able in any way to get the raw string on the topside pc.

Anybody of you is getting issue with it? Just for info, i’m running the latest blueos version 1.5.0 Beta 12

i tried to check if the service is running on the blueos terminal but with “netstat -tlnp | grep 15000” but i’m not getting any output so i guess the issue is totally on the extension as is not creating any port.

Hi @SubseaLED -

As this guide notes, the Navigator Serial ports ARE NOT compatible with RS232! Damage to that comm port input could result - you need to adapt and properly scale the signal! Since you’re getting data thru, maybe the signal is actually at 3.3V TTL voltage levels?

Please try the serial bridge again while running the latest STABLE version - beta versions are not recommended for production usage! You may also want to target the IP of the computer you’re trying to send the stream to - 192.168.2.1 typically….

You may need to take the red-pill in the terminal before you can snoop network traffic like that…
