Tryed with https://github.com/on7lds/NextionDriver/blob/master/README-using.md
too.

But the same error

[ds2k5]

after slow down the UART Speed to 115200

[Modem]
# Valid values are "null", "uart", "udp", and (on Linux) "i2c"

got this:

But the program is stopping after this message

After disabling: D-STAR, AX25,..... only DMR Enabled
the progam runs forward.... but....

Here is was I changed:

1. UART Speed to 115200
2. disable all except DMR
3. Set: LocalAddress=0.0.0.0 in [DMR Network]

[DMR Network]
Enable=1
# Type may be either 'Direct' or 'Gateway'. When Direct you must provide the Master's
# address as well as the Password, and for DMR+, Options also.
Type=Direct
LocalAddress=0.0.0.0



```But still error:
