Problem with Timer Interrupt and SoftDevice

Hi,

There is not much to go on, but clearly something happens. Can you start by building with DEBUG defined as well as logging enabled, and see if perhaps an error has been detected and the device is in the error handler?

Hi,

Thank you for your time. Meanwhile I've managed to get the app working but without the SoftDevice installed and the app located at 0x0000000 in the Flash. Also I get the the Timer to work with the ble_app_template with the SoftDevice (the app is located after the SoftDevice).

Now if i put the Softdevice (S132) in the Flash and the app at 0x26000 (In the same conditions i was when i posted) then halt the system when no LEDs are blinking, I end up with this in the console

Debugger requested to halt target...
...Target halted (PC = 0x00000A6E)
Reading all registers
Read 1 bytes @ address 0x00000000 (Data = 0x00)
Reading register (PSP = 0x       0)
Reading register (PRIMASK = 0x       0)

I also set a breakpoint in the timer_led_handler() but it never reach it.

Hi,

[quote user=""]The led 0 blink during approx. 1s and then remains off and the led 1 never turn on.[/quote]

Since this happens in the main loop, LED 0 should always blink. Since it does not, it seems likely that your application is stuck in an event handler (directly or indirectly) somewhere. Have you tried to debug? If you halt the execution, where do you end up (remember to test with a debug build with optimization turned off when doing this)?
