I'm trying to read the temperature and humidity value from dht11 sensor with cc2650 launchxl using this contiki code
contiki-ng/examples/dev/dht11/dht11.c
contiki-ng/dht11.c at develop · contiki-ng/contiki-ng (github.com)
I figure i have to change the pin to fit my cc2650 IOID, but still my board can't read the sensor (output timed out). I'm wondering if i'm using the wrong IOID pin, or i'm doing something wrong with my code format, please, be kindly take a look of the code i have change below, it'd mean the world to me if you can help me solve this problem

#include "contiki.h"

/*code i change*/
dht11_sensor.configure(DHT11_CONFIGURE_GPIO_PIN, IOID_23);
dht11_sensor.configure(SENSORS_HW_INIT, 0);

/* Wait one second for the DHT11 sensor to be ready */
etimer_set(&timer, CLOCK_SECOND * 1);
