History

This page tracks additions or changes to the AT command set based on the firmware version

number (which you can obtain via the 'ATI' command):

Version 0.7.7

The following AT commands and features were added in the 0.7.7 release:

Added AT+BLEUARTTXF (F for force) to immediately send the specified data out in an

BLE UART packet (max 20 bytes), bypassing any FIFO delays and avoiding packets

potentially being transmitted in two transactions.

Adjusted BLE UART service to use min connection interval as the tx interval

Added AT+DFUIRQ to enable using the DFU Pin for IRQ purposes when there is a

supported event on the nRF51822

Enabled the internal pullup resistor on the CS pin for Bluefruit SPI boards

Added AT+MODESWITCHEN to enable/disable +++ mode switching from the local

(serial or SPI) or BLE UART side. By default local = enabled, ble = disabled, meaning

commands can only be executed via the local interface by default.

Implemented a '\+' escape code to immediately send '+' chars without trigger the +++

delay waiting for further similar input

Added AT+BLEHIDGAMEPADEN to separately enable HID Gamepad, since iOS/OSX

has a conflict with gamepad devices causing HID keyboard to not work properly.

The following bugs were fixed in release 0.7.7:

Fixed a factory reset issue when a long delay occurs in app_error_handler()

Fixed an issue where strings were being truncated at 64 chars in UART

Fixed HID keyboard support not working with iOS 9 & 10

Version 0.7.0

The following AT commands were added in the 0.7.0 release:

AT+BAUDRATE

Change the HW UART baudrate

AT+UARTFLOW

Enable or disable HW UART flow control

AT+BLEMIDIEN=on/off/0/1

Enable/disable MIDI service, requires a reset to take affect

AT+BLEMIDITX
