About

BLEasy is a BLE (Bluetooth Low Energy) bridge for your Arduino System. It contains two type of modules which work together when pairing up.

BLEasy Host connects to the Arduino main board and BLEasy Slave connects to your shields. The main board and shields will then be connected wirelessly with each other through BLEasy.

Wires gave us headache and they also limit the size of our Arduino system. There are some BLE bridge or modules that may solve this problem, but we still find them not flexible and not easy enough to use.

Hence we decided to make BLEasy, which aims to be the best BLE bridge you can found on the market.

Wireless

BLEasy replaces wires and cable between different boards in your Arduino System.

Easy to Use

Using BLEasy will be so simple that you will feel as if you are just working on a wired system.

BLEasy will come with Arduino codes that help you handle ALL difficulties in developing coding for wireless applications.

Only simple modification on your Arduino codes is needed to make use of BLEasy!

No Smartphone / PC Needed

BLEasy is different from other BLE shields in the market, which usually need a non-Arduino host such as a smartphone or PC. No app or PC software programming is needed!

No MCU Programming Needed

Unlike universal BLE modules on the market, BLEasy doesn't require any programming on the MCU.

Only Arduino programming is needed, which means you can make use of the resources on Arudino community and build you system easily and quickly.

Real BLE Bridge for Arduino

BLEasy works as a pair: BLEasy Host and BLEasy Slave.

BLEasy Host connects the Arduino main board and add BLE capability to it. BLEasy Slave connects to the shields. The Arduino main board can then connects to the shield wirelessly through BLEasy.

On-the-Air Modification

Our BLEasy codes handle the communication between BLEasy Host and BLEasy Slave.

All programming is done on BLEasy Host side, in Arduino language. BLEasy Slave doesn't need any programming You can modify the function of BLEasy Slave, and the shields connected to it, without connecting it to the PC.

• Add BLE function to both Arduino main boards and shields.

   ~ BLE Host can also be programmed in Arduino format, making things easier, more customizable and flexible!

• Flexible usage!

   ~The I/Os in BLEasy-Slave can be freely assigned as UART, I2C, SPI, AD, GPIO. (One channel each for UART, I2C & SPI)

• Selectable Power Modes

   ~ Choose suitable mode for different power consumption and wireless data rate according to the application.

   ~ Different modes can work at the same time when multiple BLEasy Slave are connected.

• No datasheet reading!

   ~ BLEasy is easy to use. Our codes do everything for you. You will be programming as if you are working on a wired system.

• Only easy modification is needed on your previous projects to use BLEasy

• No difficult hardware design needed!

   ~ Wireless hardware design is usually difficult and costly. We do it for you and make sure that its wireless performance to be the best.

• Low Power Consumption due to BLE technology.

We have built an Arduino library for BLEasy. You just need to call for simple commands to make your shields work wirelessly with the Arduino main boards.

All Arudino Codes for BLEasy will be open source.

Note:

• You can choose any variants of BLEasy Host and BLEasy Slave for your rewards!!

• e.g. Professional Pack: 1 x BLEasy Host, 1 x BLEasy Host-EXT, 10 x BLEasy Slave Flex, 6 x BLEasy Slave Core

• The default options are BLEasy Host and BLEasy Slave Flex if backers show no preferences on rewards.

• Backer of Start Pack Lite may need to use a smartphone or bluetooth dongle to check for the bluetooth MAC address.

The above are the final PCB designs after being modified for several times. Several versions were made and tested to find out the designs for the best wireless performance and user-friendliness.

Making Prototypes
Making Prototypes

We have worked on Arduino codes that can basically work as wanted. We will keep working on it to make it more user friendly and efficient.

Before Funding

We have done PCB design for all models.

We have made workable prototypes for all models.

All functions have been tested and work in order.

During Funding

We are now fine tuning the program routine for BLE communication and user friendliness. And like how GestureR SHIELD ULTRA was born last time, we will also listen to any good advices from you guys to make BLEasy the best.

We are keeping good contact with the supplier and aim to shorten the lead time of the rewards.

After Funding

We will quickly order all the parts needed for all rewards. (~ Start of November 2014)

We will contact our co-operative factory and arrange manufacturing while we are waiting for the materials, which may have a lead time of 2 months. (~ Mid of November 2015)

Start Production (~ Start of January 2015)

After getting the manufacturing done, we will instantly start to ship the rewards. (Should start shipping around Mid to End of Feburary 2015)

Note: Exact delivery date depends on the lead time of the materials. We will try our best to fight for the shortest possible lead time with the suppliers.

Grabo Team is a collaborative team dedicated to the area of Electronic Engineering. GestureR was another successful project on Kickstarter by the Grabo Team.

Two core members of the Grabo Team:

Jonathan Yip, WingPui

  • Has worked in the R&D field for over 6 years.  
  • Possesses expertise in Software and Firmware Programming.  
  • Is equipped with experience in Sensor Applications. 

Sammel Tung

  • Has worked in R&D field for over 9 years.  
  • Possesses expertise in Hardware Design and Production Management.
  • Has established friendly networks with factories in China.  
  • Possesses the ability to ensure production to be completed on schedule while keeping the quality up to standard.

Risks and challenges

Before building the working prototypes as shown in this page, we have done several modifications on the PCB design to make it final. Several versions were made and tested to find out the designs for the best wireless performance and user-friendliness.

We will keep testing the prototypes and make sure there are no errors before manufacturing.

The lead time for some of the components is quite long. We will keep in touch with the suppliers to make sure the components be delivered as soon as possible.

There is always risk in manufacturing, especially for wireless products. We will maintain good contact with our long-term co-operating factories. We will make sure the manufacturing process is smooth and every BLEasy you receive will be of the best quality.
