In FreematicsONE.cpp, there is:

// send terminating byte (ESC)
if (version != 10) {
SPI.transfer(0x1B);
digitalWrite(SPI_PIN_CS, HIGH);
} else {
digitalWrite(SPI_PIN_CS, HIGH);
}

What is this terminating byte business and why is it needed only if the OBDUART version is 10?

BLE consistently loses characters for me. I initialize it very simply:

Code: Select all

#include "SoftwareSerial.h"
static SoftwareSerial ble(A2, A3);

ble.begin(9600);

Anyone have a more reliable way to use BLE on this Freematics logger? Anyone try AltSoftSerial and have better luck?

What is this "// send terminating byte (ESC)" in the code?

Anyone find the SoftwareSerial to the BLE unreliable?
