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.

I have a speeduino project on a Euro kart, the tuner studio is connected via a usb, all good on that front. My dash is served by a bluetoothed pixel 3 phone. Connects up straight away, the hc-05 led stays on, but the phone display dash freezes and the little realdash icon comes up ‘connecting to ecu’ then refreshes the image, this happens every 5 and 10 seconds. I realise this is a known issue, but could someone explain the work around with the serial 3 port? tunerstudio v3.2.05
Cheers
