The BL653 module is powered for an IC nRF52833 from Nordic Semiconductor. BL653 works with SmartBasic who has been designed to make wireless development quick and simple.

Goal: We will send data from our laptop using a terminal to our Android App.

Steps:

• BL653 hardware setup
• Terminal and firmware setup
• Test using our Mobile App

BL653 hardware setup

BL653 Power Up: the module is coming with a basic firmware; After power up it will reponds AT commands, then over it we will upgrade a firmware to get UART communication worring.

we are using an USB FTDI serial adapter to make the UART communication. Below the connections to upgrade the firmware:

• BL652 Pin31 to 3.3V FTDI serial adapter
• BL652 Pin 0 to GND FTDI serial adapter
• BL652 Rx to Tx USB FTDI serial adapter
• BL652 Tx to Rx USB FTDI serial adapter
• BL652 RTS to CTX USB FTDI serial adapter
• BL652 CTS to RTS USB FTDI serial adapter


• BL652 pin5 pulldown control autorun
• BL652 pin50 Pull High externally to enter VSP (Virtual Serial Port) Service.

Terminal and firmware setup

Start UwTerminalX; check the setting then OK; Go to tab Terminal then press ENTER in your computer, you should see 00 in the terminal.

Upgrade the firmware with: $autorun$.vsp.uart.bridge.configurable.incoming.sb
