AT Commands

The command interface to control the AS7225 is via the UART, using AT commands across the UART

interface. The AT command interface block diagram, shown in Figure 84 between the host MCU

interface and the core of the system, provides access to the AS7225

’s Cognitive Light Engine’s control

and configuration functions (see also chapter UART Command Interface).

In the command description below, numeric values may be specified with no leading prefix, in which

case they will

be interpreted as decimals, with leading “0x” to indicate that they are hexadecimal

numbers, or with a leading “b” to indicate, that they are binary numbers. The commands are grouped

into functional areas Texts appearing between angle brackets (‘<’ and ‘>’) are commands or response

argument. A carriage return character, a linefeed character, or both may terminate commands to the

SLD. The SLD command output is a response followed by a linefeed character. Note that any

command that cannot interpreted or which

encounters an error will generate “ERROR” response.
