To be really sure that you can connect to the device thus making you able to pair with it, you will have to make sure that the device name setting in the AT Command list is set to the name you want or need. RSSI stands for Received Signal Strength Indicator and, just like the name implies, is a value of strength of which the incoming signal has to be in order to even be considered by the scanning device.
In other words, the lower the value is set to, the weaker signals the scanning device will show. You can read about it here. I will spare you all the details about the UART protocol itself, but one thing that we will need to make sure of is that you have it installed onto your slave device.
You can download them directly HERE. Inside this file, you will find a lot of stuff. In this folder, we will have surprise surprise! As you can see, there are a TON of folders in here, but we will cherry-pick our folders here too. The main point of showing you this is simply because from these two folders, you can snatch the small amount of code that you need to edit the main code of your UART main-code so that you can both read and send the data from the sensor you might have.
This takes us to the next step:. This means that your two devices, master and slave, have now paired successfully. AT command module is an easy solution provides developers a quick breakthrough to Bluetooth connection.

Module Documentation. First time only! Compile and Download the serial pass through program below to your mbed. Last commit 16 Sep by jim hamblen. Start a terminal application program on your PC at baud and connect to mbed's USB virtual com port. If prompted for a device firmware update, go ahead and update the firmware.
This works over the air using the Bluetooth RF link. Anything typed in the phone's UART text window, will be sent via bluetooth after hitting "send" and appear in the PCs terminal window as seen below.
Any characters typed in the PC's terminal window will appear in the phone's text window as seen below. Once it is connecting and transfers text, try this demo. The program below decodes button messages from the number keys on the right side of the control pad. Hitting a button sends a text message like "!

B11" button 1 hit or "! B20" button 2 released. Compile and download it to mbed and reset. Once more keys need to be decoded for controlling something a little more complex such as a robot or game, a switch statement can be added. A template is provided in the code below.The BGX command mode is very simple. The backspace erases characters, but no other editing is provided.
Backspace operation requires vt terminal emulation or similar. These settings are provided to make it easy for a host microcontroller to parse responses by examining response headers. See Serial Interface, Response Format. A description of how to use the command, together with notes about available options and arguments.
Turn on advertising as a peripheral at the specified rate. The command adv off turns advertising off. If no argument is supplied, the default is adv high.
On reset, advertising defaults to high for a duration specified by bl v h d default: 30 secondsthen switches to low for a duration specified by bl v h d default: secondsthen turns off. Connect to a peripheral with the specified index number. The index number is obtained from the output of the scan command. This command blocks until either a successful connection is made or the command times out. It then returns a status indicating success or failure. DTM can operate in the transmit or the receive direction.
In transmit mode, the BGX's radio will continuously transmit Bluetooth packets at a fixed interval. A Bluetooth tester device should receive and analyze these packets. If more time is needed to set up test equipment between the end of advertising and the beginning of DTM, the user can manually stop advertising with the adv off command. After sending dtm stopThe user can issue the adv high or adv low command to resume advertising.
Only specified if operation is start. May be one of the following values:. Must be an integer value in the range  designating the Bluetooth channel that will be used in DTM. The frequency can be derived from channel with:.
Only specified if operation is start and direction is tx. Mmust be an integer value in the range . Note: The length is ignored if packet type is set to carrier.In this case we will just send two trivial commands, one to toggle a led, and one to disconnect. Observing the files themselves can perhaps be just as educational as following the steps below. Let's go! Attempting to compile with just NUS would quickly reveal this.
Go ahead and add the source file to the project files and the header file path to our project's include path. This amount can always depend on your device.

BGX13-1.0 Command Reference
Very helpful.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Here is a list of AT commands. And the query value will not be larger than the set one.
If you want to use this parameter, must be specified firstly, null also is valid. Begin receiving serial data. When the requirement of data length is met, the transmission of data starts.
If the connection cannot be established or gets disrupted during data transmission, the system returns:. Enter transparent transmission, with a ms interval between each packet, and a maximum of bytes per packet. Please wait for at least one second before sending the next AT command. This command can only be used in transparent transmission mode which requires single connection.
Send data of designated length. If connection cannot be established or gets disconnected during transmission, the system returns:.
If the passive mode is enabled, when ESP AT receives socket data, it will prompt the following message in different scenarios:. When the requirement of data length, determined byis met, the notification starts. If the data transmission is successful, the system returns: OK Parameters:. When the requirement of data length, determined byis met, the indication starts. When the requirement of data length, determined byis met, the setting starts.
If the setting is successful, the system returns: OK Parameters:. When the requirement of data length, determined byis met, the writting starts. Please note that the target characteristic's property has to support the read operation.
Please note that the target characteristic's property has to support the write operation. ESP32 Client: 1 Configure the characteristic's descriptor. Please note that the target characteristic's property has to support notifications.
ESP32 Server: 1 Notify of a characteristic. Please note that the target characteristic's property has to support the indicate operation. ESP32 Server: 1 Indicate characteristic. Set Command:. The AT firmware will keep waiting until the data length defined by is met, all data received will be considered as the MQTT publish message.
When the data is met, the transmission of data starts.This chip features an onboard Bluetooth stack that makes connecting and communicating with any Bluetooth 4. It also allows up to five custom public services and up to 4 custom private services, each allowing up to eight custom characteristics. When left unshorted, the PmodBLE will start up in standard application mode.
When shorted and power cycled, the board will go into test mode, which is used to update the firmware on the RN The pins on the pin header are spaced mil apart. The PCB is 1. In this way you can communicate wirelessly between two embedded devices without complicated software like is required with WiFi or Communicate wirelessly with simple serial prints and reads!
By default, the UART interface uses a baud rate of The startup baud rate may be customized to predefined rates or set to a specific user customized baud rate ranging from bps to kbps. When in command mode, the module will respond to a large number of commands allowing the user to customizing the module for specific applications.
The reset pin RST on J1 is active low. This hard reset performs similarly to a power cycling of the device. The schematics of the Pmod BLE are available here. Toggle Navigation.
