why use 50ms and 400ms connection interval for testing the maximum data throughput(2M,247byte payload)?
Because 50ms can only send a pdu , and 400ms can send up to 8 pdu...

Hello All,
I am new to this forum, I have been using nRF51822 for a while, and its a great little BLE chip. I am usinga BLE keyboard to send a key to iphone and I captured...
The purpose of this blog is to provide a step by step guide to help a developer, starting off with the Nordic Semiconductor nRF51 DK, to get the necessary tools installed and get the software (SW) development…
Hi all,
I implemented a simple multilink NUS central based on s130 for nrf51 chip-set. It means that this NUS central can connect to several peripherals simultaneously and send data to each one of them…
This tutorial will take less than 15 minutes.
#Motivation
Never lose a BLE connection when debugging your applications again! This technique will also be useful for any application using the PWM peripheral…

Setting up the Timeslot API
When you want to use the radio while still maintaining a BLE connection or have a task that you need to do uninterrupted by radio activity, you can set up a timeslot. The timeslot…
Radio Notification
In this tutorial we will set up a beacon example and modify it to use radio notification. Then we will use radio notification to light a LED when the radio is transmitting.
While this…
Board Support Package
In this tutorial we will use the Board Support Package to control hardware peripherals on the nRF51 or nRF52 DK.
