Problems with reading success

Hi,

I am having a problem with reading values from the obd connectior. I do get like 12 % of reading successfully and rest fail. adapter is I2C model and connected to a golf mk6. I am reading 8 values one after another, do I have to make some delays to the process between reads or what?

2014-03-27 09:49:56 I'm also having slow obd.read when I'm reading more than 1 sensor on a 2011 Mazda 3.
It will run super fast with one PID but if I add 2 I get over 10 seconds before the data refreshes.

Here's a code snipet

if (!obd.read(PID_SPEED, value)) {
return;
}

test_string = String(value);
test_string = test_string + " ";
CTE_LCD.Put_Text(test_string,500,0,BVS_34);

if (!obd.read(PID_COOLANT_TEMP, value)) {
return;
}

test_string = String(value);
test_string = test_string + " ";
CTE_LCD.Put_Text(test_string,120,34,BVS_34);

if (!obd.read(PID_ENGINE_LOAD, value)) {
return;
}
test_string = String(value);
test_string = test_string + " ";
CTE_LCD.Put_Text(test_string,500,34,BVS_34);

if (!obd.read(PID_THROTTLE, value)) {
return;
}

obd.read(PID_THROTTLE, value);
test_string = String(value);
test_string = test_string + " ";
CTE_LCD.Put_Text(test_string,120,68,BVS_34);

2014-02-28 05:31:34 I just bought a elm327 bluetooth dongle and it works just fine. I have like 5 sec intervals between reads(I am aiming for 5 HZ however). What to do next? mklaenius
