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...
Loaded Softdevice S140, ( Using NRF52840 DK board ) using NRFgo Studio.

I am trying to communicate between nrf51822 and Android device using Gatt. But nrf51822 invokes UartService.ACTION_GATT_DISCONNECTED after some time, the disconnection happens...
Hi,
until today we develop our application on Nordic DK with nRF1422 with 32 KB of RAM.
We are using S130 and SDK 8.1.0.
Today we saw that our target module, the MBH7BLZ07...
Hi!
I'm working with nRF51DK with s110 soft device on it. I'm trying to write simple custom service which reads some data from sensors and send it over BLE to Android app...
Hello,
I know the current limit of 15mA to share among all gpio pins.
If I source/sink current in very short bursts (100ns every 1ms) can I draw larger currents than 15...
Dear All,
We are working on a custom board with NRF51822.Everything works fine apart from the timer. What we are doing is that once the board is booted, it reads some values...
Situation:
We are building BLE device that have GATT service showing a analog sensor value.
AIN2 is connected to the sensor. AIN4 is connected to battery.
We would like...
Hi.
I use nrf51822 rev.3 build number CEAAE00(0x0079) package is WLCSP.
Before I got a experience already develop wearable device using rev.1 chip. And that board work...

I was wondering if the Master Emulator API requires the Segger IC on the nRF51 Dongle (PCA10031) to work? Or is this just used for programming the nrf-device via USB?
The...
Hi.
I'm using latest version of nrf51-pwm-library to test if PWM works fine, but unfortunately, it's not. I have very simple program which should fade LED from 255 to 0...
Is there an application note or specification that defines the term flash memory endurance and flash memory retention?
What failure modes can be expected when these specs...
Hi.
I faced very weird problem.
below is my structure of custom array;
if I set MAX_MYARRAYCOUNT as 20, it's OK.
but if I set MAX_MYARRAYCOUNT as over 30, device crushed...
