UART to Bluetooth Interfacing - EEWeb

A universal asynchronous receiver/transmitter (UART) is the most popular protocol used for talking to a computer device over serial port. What I am talking here is not exactly UART in traditional sense. It's an emulation of serial port over BLE. It's not part of profiles defined by Bluetooth SIG. It's a custom defined service. It's so popular that it has become a standard. It's an equivalent of SPP (Serial Port Profile) in Bluetooth Classic but community defined. Almost all (Nordic, Adafruit, mbed) BLE hardware providers support it. I think since Nordic started it. They defined the UUIDs and details of the service ➡️ Nordic UART Service (UUID: 0x0001). The UUID of the Nordic UART Service is 6E400001-B5A3-F393-E0A9-E50E24DCCA9E. As of now every vendor uses these UUIDs for UART. Nordic's UART Android client is a great application if you like to test your UART implementation. It's Open source and available on Play store.Below is the configuration of the Service and Characteristics that I used on a hardware device (Server or GATT Server) and then I used nRF UART 2.0 Android app (Client) to connect. The service definition below is for GATT Server. Characteristic names are from client's point of view. For testing purpose you could import this into nRF Connect and make it a GATT Server. Then you can use nRF UART 2.0 to connect and then to chat. One can implement custom protocol over that chat. Since the services above are implemented on the GATT Server. The TX Characteristic will have the WRITE permission enabled so a client can write where as a client can only READ from a RX Characteristic1. Essentially two characteristic work like register to which a client can write or read from. The picture below should make it clear.

If interconnecting two IOGEAR Bluetooth serial adapters, this must be done on both adapters. For details on using the HyperTerminal configuration menu, please see Appendix A on page 31... Page 32: Specification Specifications... Page 33: Appendix A-Hyperterminal Menu Appendix A Appendix A HyperTerminal Menu The IOGEAR Bluetooth serial adapter has a built-in configuration menu that can be accessed via HyperTerminal in Windows systems. For instructions on how to invoke configuration mode refer to Advanced Configuration section of this manual. Page 34 Appendix A IOGEAR GBS301 CONFIGURATION MENU 1. Search for Bluetooth adapter 2. Change local device name 3. Set authentication mode 4. Set pin key 5. Set encryption mode 6. Set baud rate 7. Change uart settings 8. Display device settings C. Page 35 Appendix A Option 1: Search for Bluetooth adapter Use this option to search for another IOGEAR Bluetooth serial adapter. This option is only available if device set as Master. Keep in mind that the other serial adapter must be set to slave in order to be discovered. Page 36 Appendix A Option 4: Set pin key The default PIN key for the serial adapter is “1234”. If you wish to change this to something else, use this option Option 5: Set encryption mode Use this option to enable/disable encryption mode. For example, there are some applications that might not work properly if encryption is enabled. Page 37 Appendix A Option 6: Set baud rate The dip switches on the serial adapter allow you to set baud rates ranging from 9600 to 921600. If you need to use a lower baud rate – like 2400bps or 4800bps – use this option. The baud rates available for this unit are listed below: Baud rate setting Baud rate selection from switch... Page 38 Appendix A Option 7: Change uart settings For certain applications, you might need to change the default UART settings. Below are the available options for this adapter: Parity : None, Odd, Even Stop bits: 1, 2 In case you are wondering, UART stands for Universal Asynchronous Receiver/Transmitter. Option 8: Display device settings Use this option to display the current settings of the serial adapter Option C: Clear pairing information... Page 39 Appendix A Option D: Display firmware version Displays the firmware version of the Bluetooth serial adapter; this is mostly used for troubleshooting purposes Option F: Restore factory settings Use this option to restore all values to their factory settings. Option E: Exit configuration This option is used to exit the configuration menu, and apply all changes made...

We want to change settings of HC-05 Bluetooth module like change password for connection, baud rate, Bluetooth device’s name etc.To do this, HC-05 has AT commands.To use HC-05 Bluetooth module in AT command mode, connect “Key” pin to High (VCC).Default Baud rate of HC-05 in command mode is 38400bps.Following are some AT command generally used to change setting of Bluetooth module.To send these commands, we have to connect HC-05 Bluetooth module to the PC via serial to USB converter and transmit these command through serial terminal of PC.CommandDescriptionResponseATChecking communicationOKAT+PSWD=XXXXSet Passworde.g. AT+PSWD=4567OKAT+NAME=XXXXSet Bluetooth Device Namee.g. AT+NAME=MyHC-05OKAT+UART=Baud rate, stop bit, parity bitChange Baud ratee.g. AT+UART=9600,1,0OKAT+VERSION?Respond version no. of Bluetooth module+Version: XX OKe.g. +Version: 2.0 20130107 OKAT+ORGLSend detail of setting done by manufacturerParameters: device type, module mode, serial parameter, passkey, etc.Alternate options for HC-05 Bluetooth ModuleHC-06 Bluetooth module: This is a similar module to the HC-05, but it is limited to a slave role only. It has a smaller form factor and is generally cheaper than the HC-05. However, it does not support some of the advanced features of the HC-05, such as the ability to enter AT mode to configure the module.HM-10 Bluetooth module: This is a more advanced Bluetooth module that supports Bluetooth 4.0 (BLE) and can act as both a master and slave device. It also supports a wider range of AT commands for configuring the module, and has a longer range than the HC-05. However, it is generally more expensive than the HC-05.RN-42 Bluetooth module: This is another Bluetooth module that supports both the SPP and HID profiles, similar to the HC-05. It has a longer range than the HC-05 and supports faster data rates. However, it is also more expensive and may require additional configuration to work properly.ESP32 Bluetooth module: This is a powerful Wi-Fi and Bluetooth module that includes a dual-core processor and support for both Bluetooth Classic and BLE. It is more expensive than the HC-05, but offers more advanced features and capabilities.nRF24L01+ Wireless module: This is a wireless module that operates at 2.4GHz and uses a different protocol than Bluetooth. It is generally cheaper than
