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,

Dear SOC developpers,
As many kickstarters i bought an RFDUINO kit, then I made a cool prototype thanks to the easy Arduino compatibility. I'm now thinking of industrializing...
Is there a simple software code example how to configure an interrupt handler for a single GPIO-pin? I am using nRF51822 chip with softdevice S110 and the interrupt source...
My question a little weird. Because I am super beginner about BLE. So what I want is how to write string data. now i am looking to information about this. I cannot find it...
Hi
I'm trying to implement bonding in a device based on the S120. As counter part i've used a S110 device or an iOS device (realized with LightBlue App).
While searching...
Hi All,
I am using nRF51422 and now doing ANT+ certification test with tool v1.3.6. And i find out some problem with the received value on my display in case of following...
