Can't read GPS data over BLE

Post by Gringoire »

Hello Everyone,
just bought and connected an OBD 2 adapter with BLE to an ECUSim 2000 ECM Simulator.

I connect to the BLE and i register to the characteristic notifications, receiving Gyroscope data, accelerometer and gps, but i can't receive any data from ECM like RPM or Speed. Also the ECUSim Link led is not blinking.

I'm converting the data received from the adapter in this struct

Code: Select all

typedef struct {
    uint32_t time;
    uint16_t pid;
    uint8_t flags;
    uint8_t checksum;
    float value[3];
}


At the moment i don't have (yet) an usb adapter so i can't connect the obd2 adapter to my mac. Is there something i should do in order to make it work with the default firmware (write commands on the FFE1 characteristic for example? If yes, which commands are accepted?)

Thank you in advance for any help. i appreciate any answer.

Ok, i got the obd data working, but the GPS data longitude, latitude and altitude are always 0. Is something missing there? Any help please?

Is the device exposed to open sky?
