Hello, using a FX30 with a serial extension, I’have tried to use the new firmware for my appli but I cannot have the /dev/ttyHSL1 device for my app (AT!MAPUART=17,2 not working).

you can use /dev/ttyHS1 port if you use this AT!MAPUART setting

Is it possible to use ttyHS1 instead of ttyHSL1 ?

I did try an echo on the device but nothing appears on the console.

With AT!MAPUART=16,1, it is possible to have the linux console on the good tty but AT!MAPUART=17,1 did not work.

when you set “AT!MAPUART=17,2”, the generated port ttyHS1 is for data communication on UART2, not for echo something on the console.

Ok, it works with ttyHS1. But with version 18.06 it was ttyHSL1…
