Conflict with SWIIRQHandler in nrf notification manager and app timer.o

[trk]

Hey everyone, when i was trying to compile i got this error which says

._build\ble_app_bci.axf: Error: L6200E: Symbol SWI0_IRQHandler multiply defined (by nrf_notification_manager.o and app_timer.o).

But i cant find nrf_notofocation_manager.o anywhere in code. So how to resolve this error.

You must be linking with either the ESB or the Gazell libraries - the IRQ handler comes from there. There's an app_timer_ble_gzll.c file which I think uses SWI1 instead.

@trk: There must be a reference or a file named nrf_notification_manager.c in your project. Could you try to do a Full text search in your project (Ctrl+Shift+F in KEIL ) for "SWI0_IRQHandler"?

[RK]

That's possible but I think he'd know if that were the case, there isn't such a c file in the SDK and it would be quite coincidental if he happened to write one and happened to put an SWI0 interrupt handler in it .

If you 'nm' the esb or the gzall libraries you find the following

> nm esb_gcc.a
....
nrf_notification_manager.o:
    000000ac T SWI0_IRQHandler
    00000088 C nm_status
    00000034 T nrf_nm_add
....

Which shows SWI0_IRQHandler coming from nrf_notification_manager.o. I'm 99.9% certain that this is coming from linking in one or other of those libraries.

@RK: I agree

Thanks for reply @Hung Bui @hung Bui, i dont have c file named notification manager.c. My code works for both ESB/Ble one at a time. I have earlier version of code without esb, i dont see a problem with SWI0_IRQHandler. When i integrated ESB in project and ESB is working fine. When i enable BLE by disabling ESB in the ESB integrated code, SWI0 error keeps popping out. Any thoughts on solving this error may be by disabling some parts of code?
