We are configuring the watchdog like this:
// Watchdog
NRF_WDT->CONFIG = (WDT_CONFIG_HALT_Run << WDT_CONFIG_HALT_Pos) | ( WDT_CONFIG_SLEEP_Run << WDT_CONFIG_SLEEP_Pos...
So I've got this long characteristic which takes several read operations with offsets to read it completely. Idea is to have it refreshed only after the client has read it...
Hi all,
I've have written a debug version of our application firmware to catch any and all error seen during operating. The most common one I see is NRF_ERROR_BUSY stemming...
Hello,
I am doing some tests with the Heart Rate Service Sample Application for the nRF51822 evaluation board (PCA 10001). Inside the ble_stack_init(), there is this call...

Is it possible on the nRF51822 to surface an every from the Soft Device whenever a client attempt a scan (is it SCAN_REQ?)
This is for an iBeacon implementation where I...
I'm doing some work with the nRF51822 smart beacon kit. I tried to do an over the air firmware update of the application, but kept getting dfu invalid state (2) errors after...
We've got an application (not using SD or SDK functions) that locks up the nRF51822 and does not reset even though the watchdog is configured and confirmed to work in all...
The release notes for SD 8.0 note "The default behavior is now that the application can use the CPU while the radio is active".
Does this mean that this code is no longer...
Hi,
I am trying to connect the demo board nrf6929 to my demo nrf51822 (PCA10001).
