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...
we use
peripheral: exemple ble_app_blinky
central: exemple_ble_app_bliky-c
Instead of a button we have a Switch.
When we set the Switch to "on" the led go on.
That...
Hi, I made a device with using NRF51822, named 'allb' the wearable device for babies.

We're planning to make a new version of it with using nRF52840...
The firmware used operate properly in the past, but it no longer does after we replaced the MCU(nrf52832).
During SOFTDEVICE_HANDLER_INIT, the MCU is stopped.
The previous...
I am working on a peripheral. This peripheral is IO display only. On the other side, the central is keyboard + display. I have a single, custom service with a single characteristic...

Hi ,
I have recently bought a nRF5232 PCA10040 development kit and i am trying to interface nRf52832 development kit(Master) with AS3955(slave) over twi. I tested the twi_scanner...
Hi all
I'm trying to build a generator based on NRF52832. Outpit signals are: 8MHz clock and two latches signals highly sinchronized with clock - RGB_LAT and TXT_LAT. For...
Hello,
I have a question on how to calculate the capacitance based on oscillator relaxation for NRF52. For example, in the Csense_drv example, when pin is touched by finger...
Hi,
