# BLE11x Serial Bridge
This is a firmware for creating a BLE to serial UART bridge using Bluegiga's BLE11x modules. This project is inspired by the awesome work of Dr. Michael Kroll and Jeff Rowberg with Bluegiga's BLE modules BLE112 and BLE113. Some code used is from BLE-Shield
The BLE11x pins are used as follows:
TX P0_4
RX P0_5
Module Wakeup P0_7 (Pull it DOWN to wakeup the module from sleep and wait at least 1ns before send data)
HCI Wakeup P1_1 (The module pulls it DOWN before send data to wakeup your HCI in case is required)
Status LED P1_0 (Will be HIGH when connected and LOW in advertising mode)
*HCI = Host Control Interface or also knows as your microcontroller
Simple UART Service - UUID 15AC87B6-022A-430E-9FB3-31EBB8D0BEAF
<- Characteristic RX - UUID EF84F28A-B51E-49FE-9FD6-F25B05C2C4A0
-> Characteristic TX - UUID 2CB8ADAC-7402-47FF-9937-A841CA766CA5
NOTE: This build process is only needed if you want to customize the default name of the device (SerialBridge) and some other information about the device included in the firmware.
Customize your firmware by editing config.js and entering your desired values.
/**
* Configure here
*/
module.exports = {
bluegigaModel : "ble112", // "ble112" or "ble113"
deviceName : "SerialBridge", // Max 13 chars
manufacturerName : "Kalanda", // Max 20 chars
modelNumberString : "SerialBridge 1.0.0", // Max 20 chars
firmwareRevisionString : "1.0.0", // Max 20 chars
hardwareRevisionString : "1.0.0", // Max 20 chars
}
To build files (needs NodeJS installed) with your customized config run:
# node build.js
Now the folder /build has all files with the customized values.
To update the firmware to your BLE11x module you need a CC Debugger and programmer from Texas Instruments.
The firmware is tested with v1.3.2 build 122 of Bluegiga SDK
Open project.bgproj at folder build" with Bluegiga BLE SW Update Tool to compile and update firmware to your BLE11x module.
