Error getting ranging data vl53l5x 8x8 mode.
When i measure my distance in 4x4 i don't have any issues at all. But I need to change it to 8x8 for my project.
To my knowledge you only need to change the resolution with vl53l5cx_set_resolution() to 8x8 and adjust the frequency accordingly. I have checked if my sensor is measuring with my webcam and it is a solid red light so not blinking or anything. And when i check the output it gives me this:

Error while checking for data ready on device 0.
The data not ready is just waiting till it has measured but then i get an error from the vl53l5cx_get_ranging_data() for some reason and after my sensor is obviously done till restart. Does anyone know what I'm doing wrong?
This is the relevant part of my code:
for (int dev = 0; dev < NUMDEVICES-1; dev++) { // Loop through each device
// Power on each sensor separately by setting it's LPN pin high
HAL_GPIO_WritePin(VL53L5CXLpnPorts[dev], VL53L5CXLpnPins[dev], GPIO_PIN_SET);
HAL_Delay(15); // Allow time for the sensor to stabilize
while (true) {
status = vl53l5cx_check_data_ready(&devs[dev], &dataIsReady);
if (status != VL53L5CX_STATUS_OK) {
cout << "Error while checking for data ready on device " << dev << "." << endline;
}
if (dataIsReady) {
/* Retrieve the data */
status = vl53l5cx_get_ranging_data(&devs[dev], &result);
cout << "Status ranging: " << status << endline;
if (status != VL53L5CX_STATUS_OK) {
cout << "Error retrieving ranging data on device " << dev << "." << endline;
}
for (uint8_t index = 0; index < resolution; index++) {
distanceMap[index] = result.distance_mm[index];
}
// Power off each sensor separately by setting it's LPN pin low after measuring
HAL_GPIO_WritePin(VL53L5CXLpnPorts[dev], VL53L5CXLpnPins[dev], GPIO_PIN_RESET);
HAL_Delay(15);
break; // Exit the loop for this sensor once the measurement is done
} else {
cout << "data not ready??" << endline;
}
HAL_Delay(5);
}
std::tuple<uint8_t, uint8_t> devPriority = newTuple(dev, 1);
vl53l5xLogic(distanceMap, devPriority);
}
return CONTINUE;
}
