he has an Omega2+ with FW ???
I guess - he has no dock or maybe has some custom dock
he has a CH340 USB-to-serial module / cable, it seems the Omega Tx -> PC Rx connection is broadly OK
he has a Windows ??? PC with PuTTY
@UFD BTW, regarding sound: my reason for wanting sound was background music for a game. So first I tried to get timidity working, but did not manage to get it play directly via asoc, and also found that it was a bit on the heavy side for the Omega2 with all the required instrument samples.
Then a colleague hinted me at hxcmodplayer, which can play the vintage .mod format (examples here) and is extremely lightweight. I packaged it for openwrt in my feed here, just in case ;-)
@György-Farkas Interesting, I did check on an Omega 2+ running 0.3.2 b200 and executing the command did nothing. I power cycled it, and the LED blinked through the start up pattern but the Omega-XXXX network never appeared. Now that Omega 2+ will not even start and has discoloration on the shield near the U.FL port.
I just reran the commands on an Omega 2 running firmware 0.3.2 b222 and it worked! There was no lag when the local wifi router was disconnected. Thank you very much!
@James-Solderitsch John Walicki has added some notes to his node-RED github page about installing node-RED on an Omega2+. He also advocates for the need to have a swap partition AND an extended file system to have room to install and run node-RED on an Omega2+.
