Getting Fatal error and System reset warning

[SM_]

Hi,

I tried to implement my custom service.

I followed the tutorial from this site:  https://github.com/bjornspockeli/custom_ble_service_example

For SDK 15.0 it works fine!

But on SDK 16, getting the following errors,

<info> app_timer: RTC: initialized.
<error> app: Fatal error
<warning> app: System reset

Used Device: nRF52832 of nRF52-DK Softdevice 132

Is there any change from SDK15 to 16 which will cause this problem?

Hi,

I am not aware of any problem no, though there is a slightly newer version here (15.3):

That said, I suggest you build with DEBUG (instead of release) then you should be able to get more information about the error from the app_error_fault_handler(), such as the file name, line number and error code.

Best regards,
Kenneth

Hi,

Thanks, Kenneth,

As per your shared link now I am able to discover the custom ble code in SDK 16.

Now I am trying to add multiple characteristics into the same code. (Actually, I have required 4 characteristics into 1 service)

So is it possible to add more characteristics?

I have tried but the below message received in terminal emulator,

<error> app: ERROR 7 [NRF_ERROR_INVALID_PARAM] at :0

PC at: 0x00000000

<error> app: End of error report

You should get a more verbose crash log if you add -DDEBUG to your CFLAGS in the makefile or if you are using SES see below, provided you use the default SDK app error handler (Error module):
