Hi!
We are currently writing a simple bootloader which reads the new application image from a external SPI based flash memory. We are using the S110 SoftDevice, which works...
Hi All,
I have been developing a bluetooth chip based on nRF51822 QFAC. I have followed the design rules very closely but at the end I do not get any bluetooth signal coming...

Hi
I set one GPIO interrupt with low-to-high sense, but seems it did not triggle the interrupt when SD run.
I want to confirm the SD would make the interrupt loss? If so...
Hi folks,
I have a 2MHz clock (call it DRDY) coming into my nRF51 on one of the GPIO pins (call it AFE_DRDY). I need to read an external AFE chip on every falling edge...
