Problems with keeping the connection between speeduino and tablet

Hi im having problems with realdash, i have the speeduino 202008 firmware on the ecu and i cant keep the connection, sometimes the display works 1 second other times it works 4-5 seconds before the picture freeze and it says connecting to speeduino again, and then it just repeats itself.
Any help or ideas would be appreciated
Kind regards joachim.

There has been known issues with Speeduino that we have not been able to solve. If my memory serves me right, only the Serial3 is working properly on older firmwares.
