Hello. Is there a way to clear the LED screen, after pushing text to the LED screen, without issuing a hard reset?
Have you tried the RAPI command $FP?
FP x y text - print text on lcd display
$FP 0 0 Top line text
$FP 0 1 Bottom line text
no text should clear the screen
$FP 0 0
$FP 0 1
If you are using RAPI via the Wi-Fi module, you are likely fighting with WiFi which is also controlling the screen via the same RAPI commands.
