The function should be sd_ble_gattc_write(..) (not sd_ble_gatts_write() as I wrote in my previous answer). Do you have verified that '0' is the correct connection handle?

Do you get a hardfault in sd_ble_gattc_write(..), the app never returns from that function? What does your write_params look like?

when it enter to call this function sd_ble_gatts_write(0, &write_params); , it goes to HardFault_Handler
PROC EXPORT HardFault_Handler [WEAK] B . // cursor stops at this position ENDP

When you send data to the slave, I would assume that you use sd_ble_gatts_write(..). Which error code does sd_ble_gatts_write(..) return?

After connection and it going to RTC1 interrupt making led toggle and going to this portion. HardFault_Handler
PROC EXPORT HardFault_Handler [WEAK] B . ENDP could please tell me why it behave like this.

Hi,

I got this , Now my rtc is working fine but, if i send data to slave in rtc handler it is not working. it may hanging in rtc interrupt. But connection is happens and unable to send data to slave device. here is code: if ((NRF_RTC1->EVENTS_COMPARE[0] != 0) && ((NRF_RTC1->INTENSET & RTC_INTENSET_COMPARE0_Msk) != 0)) { NRF_RTC1->EVENTS_COMPARE[0] = 0; NRF_RTC1->CC[0] = NRF_RTC1->CC[0]+(COMPARE_COUNTERTIME * RTC_FREQUENCY); // nrf_gpio_pin_toggle(GPIO_TOGGLE_COMPARE_EVENT); nrf_gpio_pin_toggle(19); //this state not changing, only once toggled. if(flag == 0) { char_write(0x14,0x13); // sending data to slave. flag =1; nrf_gpio_pin_set(19); }else { char_write(0x00,0x13); flag =0; nrf_gpio_pin_clear(19); }

The softdevice uses RTC0, it means that the RTC0 is blocked for the application when the softdevice is enabled, see the S130 softdevice specification.

When the softdevice is enabled, the application has to use RTC1.
