It delivers up to 2. 1 Basic AT Commands List. 0 The BL600 or BT900 BLE module running smartBASIC has two different modes of operation: Interactive Mode – In Interactive mode, commands are sent via the UART and are executed immediately, analogous to the behavior of a modem using AT commands. Masked-ROM: 240KB. By placing the BLEFriend module in 'Command' mode (set the mode selection switch to CMD or setting the MODE pin to a high voltage) you can enter a variety of Hayes AT style commands to configure the device or retrieve basic information about the module of BLE connection. I am having one other vendor's Bluetooth chip that is eating HCI commands overt he UART so willing now to use STM32F103 with BlueNRG BLE stack sending HCI messages over UART. As there is no EEPROM on board, it is required to load module-specific settings such as MAC address and Crystal trim at the module initialization stage. Customers who is familiar with Classic Bluetooth are used to call as SPP service. AT commands can be upper or lower case but require line end characters (\r ) Default PIN is 000000 The modules report themselves as BT05-A. the EEPROM. 0 BLE Bluetooth module, MCU can be set up,also can controlled by a remote Bluetooth device for setting,can transfer data, and can remotely control 10 PIO pins,so,the best choice is HM-10 bluetooth module. It’s not a communication protocol like SPI and I2C, but a physical circuit in a microcontroller, or a stand-alone IC. These commands are vendor-specific commands (VS) generally used for testing and debugging purposes. Tucker 8 AT Commands Over Bluetooth 9 Optimization 10 Version Differences 11 Syntax 11. Chapter 7 AT Commands with Configuration Saved in the NVS Area The HM10 is controlled via AT commands sent over the serial UART connection. When run the example will connect to the first BLE UART device it finds, send a string, and then wait to receive a string. In the example code below I am writing a simple server, once connected it responds to commands like whoami or date etc. Here is the completed sketch, Adafruit_BLE_UART_led_control. You can use any app that can send UART bytes that comply with the HCI commands in the TI_BLE_Vendor_Specific_HCI_Guide.
