Introduction
USB BLE - the LINK is the communication module based on bluetooth 4.0. It uses the USB package which is compact and compatible with MAC & Windows. Now you could use this adapter to receive/transmit data.
Two BLE4.0 can realize the point-to-point wireless transparent transmission, master-slave machine setting, wireless program burning. USBBLE also could be a PC BLE wireless programming
adapter.which support all DFRobot BLE series, like Bluno, Bluno Romeo. etc

Wireless Programming via USBBLE-LINK
In this section, we will learn how to Upload the sketch on air via BLE. It is really amazing.
Tools required
- Ble-link x1
- USBBLE-LINK x1
- Micro USB cable x1
- XBee expansion shield x1
Step by Step
The Step by Step tutorial of the USBBLE-LINK is almost the same with the Bluno.
How to Wireless Programming through BLE.
Update BLE Firmware
It is better to update the newest firmware for the better experience.
As USBBLE Link is using CC2540 chip, the method of the updating is very close to BLE-Link
Please choose BLE LINK firmware. Or it won't work. The boot button is inside of the cover, please use a male jumper cable to touch the Boot button.
Configure the BLE through AT command
There are three revolutionary BLE firmware versions now, maybe it will be more.
For the reason of unified management, we will put all BLE AT command on the BLUNO wiki page
