Hi all,
My arduino keeps randomly disconnecting from the dash board (chrome) and then comes back… Its intermittent.
Its a Wimos D2. Sketch below, but basically it polls from serial and sends the information to a virtual pin.
I put in a delay into the main loop of 5000ms to see if that helped, and it actually made it worse.
Any help would be appreciated.

const int debug = 1; //change to 0 when you are finished debugging
float bvoltage, ctemp, btemp, bremaining, lpower, lcurrent, pvvoltage, pvcurrent, pvpower;
// instantiate ModbusMaster object
ModbusMaster node;
// put something here if you want it to occur before or after transmission to the serial interface…i.e. delay etc. I have these blank and it works fine
