MMA8453 interface with BLE

[Murugan]

Dear Nordic Team,

Thanks for supporting.

Currently i am working with MMA8453 accelerometer . I already interface with nRF51422 using TWI it is working fine. The sensor interrupt pin is connect with GPIO interrupt. Everything is ok for TWI example code.

Now i want to interface ble_app_proximity example code. When i was enable the GPIO interrupt in ble_app_proximity code this application is not work. I dont know what i am doing wrong. Please support . my code main.c

My Hardware : PCA10028 SDK : 11.0

advertising_start() doesn't return anything, it's a void. I tested your project, nrf_drv_gpiote_init() returns 0x00000008, which is NRF_ERROR_INVALID_STATE. It is returned if the driver already has been initialized. You could easily have checked this yourself, just turn off optimizations and put a breakpoint on APP_ERROR_CHECK() below nrf_drv_gpiote_init();

Thank for reply. I already tested above you are mentioned i am always getting returns 0x00000000 But code is not run next line.

Have you turned off optimizations? Options for Target->C/C++->Optimization: Level 0.

[Murugan]

yes after optimization off i am getting returns 0x00000008. After command the nrf_drv_gpiote_init() this function the code is running but i cant get gpio interrupt.

Seems to be working fine here. Have you tried to put a breakpoint in the start of in_pin_handler()?

[Murugan]

yes i am tried but not yet get interrupt.
