Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
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 to all,
i am developing a device that in it i need to measure voltage of battery to report percentage of battery to user, but the voltage that i measure with ADC is different...
Hi,
after migrating from SDK12.2 to SDK14.2 we encountered a problem with GAP Security.
When setting optimization to -Os, the program fails with BLE_GAP_EVT_AUTH_STATUS...
Hi all,
I am trying to use uart-app (segger example in SDK15) to generate hex file, which will be programed to nRF52832 later with Softdevice by nRFGo Studio. ((Instead...
Hi,
we are using the NRF52840 DK and we would like to use our own antenna. We saw on others posts that we have to connect it to the J1 connector's place.
We have some...
Based on the Product Specification v1.0, the antenna load impedance should be 15Ω+j88Ω.
I checked the antenna impedance based on Figure 32.
The simulation result is...
During the development of nrf52832 (SDK14.2), I occasionally get NRF_FAULT_ID_SD_ASSERT error. When the NRF_FAULT_ID_SD_ASSERT error occurs, I can only get the information...
