Trying to simply combine sample program. (ble_app_beacon and spis)

[sgret612]

Hello.

Now, I'm trying to combine  ble_app_beacon and spis.

I succeeded in building and it generates hex file.

The problem is that the device stops sending BLE data

even if I put one line of spis code.

Deos anyone face the same problem as I have done?

Here is my main.c

Hi,

Check what the program is doing when the application stops sending data. Use the debugger in SEGGER and pause the program when it stops. Where in the application is the program stuck?

Dear Jared

Thanks for a reply. 

I carefully checked what the program doing.

And used the debugger.

However, I'm faceing another problem.

As I enable the SPI function (nrf_drv_spis_buffers_set) in main loop,

my iphone is unable to catch the signal of beacon.

btw, my BLE module is nRF52832. A thing what I'm trying is get signal from pressure sensor(MS580314-BA01).

I already found out a sample with I2C but never found out one with SPI.

Kindly redards,

Hi,

Thanks for a reply and sorry for a late reply due to the weekend.

#ifndef NRFX_SPIS_DEFAULT_CONFIG_IRQ_PRIORITY
#define NRFX_SPIS_DEFAULT_CONFIG_IRQ_PRIORITY 6
#endif

I set IRQ of SPIS 6. default setting.

IRQ of GPIO is also 6. 

Kindly Regards,

Shigeto

Hi,

I found out that it jumps to 'app_error_fault_handler' in spite of being simplified main function.

Wondering what is happing...  

'cos a beacon works fine after installing a softdevice and the built hex to device...

If it goes into the error handler then it's because a function returns an error code somewhere. You now have to figure out by using breakpoints and the debugger exactly what function that returns the error code. Note, that when you use the debugger and halt a softdevice application, you'll have to restart the program before resuming it. You can't halt the application and then resume it without restarting as it will result in the application asserting. It's explained more in detail here and here.

Hi,

Thanks for a quick reply!!!

OK. I will carefully read links that you attached.

Kindly Regards,

Hi,

I read 'em. And I got that I need an external debugger.

However, it seems pretty hard to me... ETM...

sigh... There are so many hells that I'm losing enthusiasm...

Well... need more patience... I know...

Kindly Regards,

I got it!!! I need an external debugger, which is a hardware!! Not software!!!!!!

But... Too expensive!!! I can build a new Desktop PC!!!! Can not pay for it... 

And I noticed that there is no other way to debug perfectly....
