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...
Dear,
Im trying to measure the RSSI with THINGY:91, I found on the document nrf91_at_commands_v1.1.pdf about

Hello,
I have a low power application, which is activated by a push button press. (The DC-DC converter is also in shutdown mode normally, so the NRF9160 does not have power...
I am occasionally (very rarely) getting "Mesh assert at 0x00037996", but when I try to look this up, I get:
My understanding is that this means the mesh_assert is...
Hello, this is the nrf52833/52820 design drawn by the customer, because this is our first contact, please help to check whether it is reasonable? thank you.
Hello,
I'm working on a BLE app on an Arduino Nano 33 BLE, which is equiped with an nrf52840. I'm struggling to increase my BLE transfer speed ( i think due to the limitations...
Actually i was working on 3 boards, nRF51422,nRF51822 & nRF52840. While executing some examples on each board i realised that each board has its specific pca hex file to be...
I n the main of my program I have this( UBLOX_PWR_PIN = Pin16 of nrf ),

Hello,
I've a problem with a PPK board.
When the current go over 10mA the value reported is wrong, in my case should be 15mA and PPK measure 80mA and more. Instead, in...
Hello,
I am working on a project that is using nrf52840 chip as a peripheral and the product is supposed to last and run for 25 years. During that period the device will...
Hi everyone I have been reading the GPS data using nordic nrf52840 over the UART. I am able to receive as much as 64KB of data via the UART. Here's the scenario of whats been...
Hi All:
Applyed the under timeslot :

I am trying to get the maximum Tx power from the nRF5340 PDK.
The nRF5340 specifications say that setting VREGRADIO.VREQH is required to get the last +3dBm of transmit power...
Hi,
I know that this topic has been raised here many times, and I did read all of those threads, however none of them seem to solve my problem. As many others, what I am...
