I would like to test the newly added v4.2/v5.0 Bluetooth features (e.g. LE Secure Connections, Data Packet Length Extension, 2xSpeed, etc) against non-nordic devices. I have...
I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
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...
I am working on two devices, a peripheral and a central. The peripheral is custom hardware. The central is being run on a Rigado BMD-300 series evaluation kit. I'm using Segger...
Hi,
Perhaps this question is too basic, but I haven't been able to find this anywhere.
I've followed this tutorial successfully with an nRF52832 DK:
However, I'm missing...
Hello,
I wanted to create an SPI shell, similar to what is available for I²C. I am therefore trying to create a generic SPI device in the devicetree:
Somehow I am...
Hello,
We use nRF52840(0dBm)+nRF21540(Dec6).
In the case of using nRF52840+nRF21540, tx spurious emissions occurs severely in the nRF21540 output.
FEM(nRF21540) output...
Hi.
I am developing a custom board using the NRF52840. The mcu needs to connect to a modem and a gnss module. Both modules will communicate with the mcu over UART
I'm...
I'm working on a prototype that has 8 BLE sensor nodes that are powered by coin cells and placed on different parts of a human body.
The host node is the main processing...

Hello,
I have one central and one peripheral device connected over BLE. The peripheral has a custom service characteristic containing the firmware Version value. After connecting...
On a custom board we are using an RTC chip to generate the 32khz clock.
I have verified that the hardware register is set to external, bypass, and the src is xtal. The clock...
