Bug on RealDash CAN + Arduino???

General Bugs and troubleshooting
1

Hi, Guys.
I thinh that i found some bug on RealDashCan,
So, when i send Frame to Realdash, if i dont send frame 3200, 3201 and 3202, RealDahs show me delay, like 0.5s.
It seems that there is packet loss in the reception of data

Ex with problem
memcpy(buf, &rpm, 2);
memcpy(buf + 2, &kpa, 2);
memcpy(buf + 4, &clt, 2);
memcpy(buf + 6, &tps, 2);
SendCANFrameToSerial(3200, buf);
memcpy(buf, &digitalPins, 2);
SendCANFrameToSerial(3201, buf);

Ex OK
memcpy(buf, &rpm, 2);
memcpy(buf + 2, &kpa, 2);
memcpy(buf + 4, &clt, 2);
memcpy(buf + 6, &tps, 2);
SendCANFrameToSerial(3200, buf);
memcpy(buf, &digitalPins, 2);
SendCANFrameToSerial(3201, buf);
SendCANFrameToSerial(3202, buf);

I took the Basic Arduino example. Commented out the line 129:

//SendCANFrameToSerial(3202, buf);

And tested with Windows version of RealDash. No slowdowns detected of any kind. Is there something else you have changed on the example?

Khadas 1 - Android Version;
Arduino Mega 2560
.xml - same of example
.ino - comment line SendCANFrameToSerial(3202, buf);

I do believe that there is a problem (and can see it from the video). But I’m unable to fix anything that I cannot reproduce on my own test equipment. Unfortunately I do not have Khadas VIM to test on, if it is something related to that.

The point is that Vim 1 is too slow with a lot of indicators with arrows.
