I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
Hi,
We use the nRF51 (nRF51822) on our products with the S130 SDK 2.0.1. In order to update the BLE application that we developed, we use the bootloader (secure bootloader...

Hi,
I'm interested in passing a PWM wave form to drive a motor using an Allegro A4963 . There exists an Arduino library that does just that and in order to set speed they...
Hi,
I have recently received some nrf52840 Development Kits. It is written on the boxes: "Electrostatic Sensitive Devices! Do not open or handle except at a static-free...
Hello Nordic team,
I am trying to develop a long button press handler, but I am unable to find the proper documentation or example code to help with that. I am not sure...
Hi,
The overview page at https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52.html is very useful.
One thing would make it better:
If you could please list...
Hi,
I am implementing a PC application connecting with nRF52840 dongle as central (s140). I am bonding with a BLE peripheral device following this sequence diagram . Application...
Hello,
I have been trying different mode under SYSTEM ON configurations and I can not get anything below 1mA.
My application required to keep nRF52840 (I use BMD-340)...
Hi all
1. We want to use the new radio nRF5340. Is it fully pin ompatible with the older nRF52840? (Antenna, programming interface, clocks, supply, etc.)
2. On the nRF52840...
