Setting baud rate for /dev/ttyUSB0

Submitted by rbreuss on Sun, 24/05/2015 - 08:12

Im running Emonhub at RasPi with USB Jeelink instead of RF12 RPi. So my serial communication goes through /dev/ttyUSB0 (changed in emonhub.conf). Everything work fine at 9600 Baud, but now I would like to make it faster and to increase baud rate to 38400. I can do it via stty -F /dev/ttyUSB0 38400 command, but after rebooting is it back at 9600. Does someone has a tip, where could be changed this baud rate to 38400 permanently?

Hi Radek

The baud of the JeeLink is hard coded into the sketch, but setting the serial baud in emonHub is pretty straight forward, just add the line "com_baud = 38400" to emonhub.conf in the init_settings for the interfacer where you set "com_port = /dev/ttyUSB0".

Thanks Paul. I do confirm, your solution works as expected. I have changed baud rate also in Jeelink sketch, so now my communication runs at 38400 baud. Thanks
