Hi!
I wonder what is the GPIOs nominal voltage level when I'm using the internal DC/DC converter?
I know that the internal DC/DC converter output voltage is 1,9V but I...
Hello,
we made PCB based on reference with ST balun. In circuit the low freq crystal is optional, so we didnt use it. In software i noticed app_timer use RTC timer. So the...
I am trying to bootload an extremely large hex file using a slightly modified DFU (modified from SDK v5.2.0's example)
The problem is that the hex is so large that eventually...
Im having errors like Arduino is in the while(1) loop if I enable the DC/DC converter in the characteristics and generate service.h file , If I do not use this setting everything...
I have a NRF24L01 board, which acts as a receiver. It listens on RF channel 2 using address pipe 0 address as follows 0xC47B4D0331. I am able to transmit to this NRF24L01...
I need to wake my uC from sleep when the nrf8001 gets in connected mode and for that I need to supply an external interrupt on hardware interrupts on the MCU.
Will active...

I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi
In my project, we wanna transmit large amount of data from UART master to nRF5182, and then to iOS7. Baud rate is 19200. Feed-in speed is near 2KB/sec. BTLE transmission...
