RE: Zephyr ti_tmp11x driver fails with -16 (EBUSY)

hi,
I was able to solve the issue.
I had to explicitly set the 'Sampling Frequency' property in the driver to force the device out of Shutdown and into Continuous Mode.

also the original code treated "sensor_sample_fetch()" failure as a fatal error and exited the program. The TMP117 sensor often returns (-EBUSY) for the very first sample (or if polling too fast) because the conversion data isn't ready buffer yet.

Thus i changed 'return' to 'continue' inside the while loop and was able to read the value on the 2nd loop iteration

while (1) {
    ret = sensor_sample_fetch(dev);
    if (ret) {
        printk("Fetch failed (%d), retrying...\n", ret);
        k_sleep(K_MSEC(1000));
        continue; // <--- THE FIX: Just wait and try again!
    }
    // ... Success ...
}

Hi!

Could you post some sample code that shows what you are doing ?
