CCS/LAUNCHXL-CC1350: Ti 15.4 Stack Sensor/ collector example

Tool/software: Code Composer Studio

Dear experts,

now i am trying to transmit sensor value through sub 1 ghz, i was open some thread about this task they are suggest to try Ti 15.4 Stack Sensor/ collector example. now i am working with that that is working fine then i am trying to reduce reporting interval based on this method http://dev.ti.com/tirex/content/simplelink_academy_cc13x0sdk_3_10_01_00/modules/154-stack/154-stack_01_sensor_collector/154-stack_01_sensor_collector.html now my sensor module not respond to my collector. what can i do, i was made changes based on the above page.

Changes:

Sensor project-->Application folder---> Subg folder---> config.h file 

#define CONFIG_REPORTING_INTERVAL  500              //180000

then 

Collector project-->Application folder---> Subg folder---> config.h file 

#define CONFIG_REPORTING_INTERVAL 1000 //90000
/*!
Polling interval in milliseconds to be set on connected devices using
configuration request messages. Must be greater than or equal to default
polling interval set on sensor devices
*/
#define CONFIG_POLLING_INTERVAL 100 //6000

next 

Sensor project-->Application folder---> Sensor.c file

#define MIN_POLLING_INTERVAL 100                          //1000

collector board is print    !Responding: 0x1    to my uart, what is the problem here, can you help me to find the mistakes what i make.

thank you
