Hello :)
For the code below, why are we defining the _wfi while in the code we only use _WFI() for addressing the function? Also once we use _asm volatile ("wfi); isnt the...
Hi:
my sdk is about 96k,and i use 51822QFAC,but it's flash is 256K,(256K-88K)/2=84K,so it is not enough for me,how should i do,if i add a external flash is ok or do you...
Plz help me with code or sequence of steps being followed by _WFE() or power_manage() functions. by which they manage the nrf51422 to run in low power mode.
So that i can...
Hello,
I'm developing a custom UART through BLE using NUS. I've been testing my idea on the nRF51822 USB Dongle and it worket perfectlly (compiling on latest Keil V5),...
Okay, I know there's a lot of threads about the subject. I have tried to read them all, with no help. My device still consumes 1.4 mA. Resetting does not help, so I assume...
One more silly question for today ~
This devzone is really a great tool, it saves us a lot of time each day, and I'm sure we would remember each contributor better if they...
Hello, I use the example ble_app_hrs_c_s130_pca10031 with the nrf51 dongle (#define ENABLE_DEBUG_LOG_SUPPORT) and a nrf51822 as a ble sniffer. In addition i use 2 Polar H7...
