Hello Jared,

bt_bas_set_battery_level() function is used for updated battery level. You have to scale your battery to the correct range while calling this function.

Valid range for bluetooth battery service is 0-100, so the function reports failure if you set a higher value:

Hello Kazi,

I hope your sick child gets better soon!

Sorry to be confusing with the BAS return 22. It's from the bas.c file. See the code snippet below. I'm just trying to understand the code.

#define	EINVAL 22	/* Invalid argument */

int bt_bas_set_battery_level(uint8_t level)
{
	int rc;

	if (level > 100U) {
		return -EINVAL;
	}

	battery_level = level;

	rc = bt_gatt_notify(NULL, &bas.attrs[1], &level, sizeof(level));

	return rc == -ENOTCONN ? 0 : rc;
}

Best regards,

Jared

Hello Jared,

Sorry for the late reply. I am out of office with sick child.

I have one question to ask you:

1. What do you mean by ''BAS return 22'' ? Could you please post some console output from your program?
