Service Event Double Trigger

Hi Bjørn,

I have move all the code that interface with services and characteristics handles to the service_hal.c files (this is in the main app). The macro is still in the .h file. The only global data is the information that will get sent to the service.

Making the veritable static broke the definitions in main.c. The characteristics had garbage in as there init values.

PS: Can I ask you to use my screen name please as this is a public ticket.

Regards

Hi Luloff,

I think it is because you have added the

BLE_IO_CONTROLE_SERVICE_DEF(io_controle);

macro to service_hal.h. Which is included in both the service_hal.c and main.c. This means that the

NRF_SDH_BLE_OBSERVER macro will register the ble_io_controle_service_on_ble_evt callback twice.

You should add it the same way as BLE_DEVICE_INFO_SERVICE_DEF, i.e. in service_hal.c.

Best regards

Bjørn

Hi,

I have just resolved this issue. I did not declare the variable as static in the macro to add the service to NRF_SDH_BLE_OBSERVER().

//Fault version

#define BLE_IO_CONTROLE_SERVICE_DEF(_name) 		\
ble_io_controle_service_t _name;			\
NRF_SDH_BLE_OBSERVER(_name ## _obs,					\
                     BLE_HRS_BLE_OBSERVER_PRIO,     \
					 ble_io_controle_service_on_ble_evt, &_name)
					 
// Fix version					 
#define BLE_IO_CONTROLE_SERVICE_DEF(_name) 		\
static ble_io_controle_service_t _name;			\
NRF_SDH_BLE_OBSERVER(_name ## _obs,					\
                     BLE_HRS_BLE_OBSERVER_PRIO,     \
					 ble_io_controle_service_on_ble_evt, &_name)
