2.3.23 S:,<H16>,<data>

This command is used to change any settings in configuration EEPROM.

This command expects two parameters. The first parameter is a 16-bit hex value that

represents memory address of EEPROM of the first byte of data. If there is more than

one byte of data to be written, the memory address automatically increases. Set the

second parameter value with the following format:

• Hex values up to 32 bytes.

• ASCII values up to 32 characters; enclosed by a quote

User must understand the mapping between EEPROM memory address and

configuration parameters for the RN4677.

Default:

N/A

Example:

2.3.24

S>,<0,1>

Command S> enable or disable command prompt. If command prompt is on whenever

RN4677 is ready to receive a command, prompt CMD> is sent to UART to notify user

that RN4677 is ready for next command. This feature releases the host MCU load to

keep track of command response and timing requirements.

Default:

Example:

GET COMMANDS

The Get commands retrieve and display the stored information of the device. Most of

these commands do not have a keyword or character and do not take any parameters.

2.4.1

This command displays basic settings such as the address, name, UART settings,

security, pin code, bonding, and remote address.

Example:

S:,0010,414243

// Set device name to be "ABC", where device

// name is stored in EEPROM starting from

// memory address 0x0010

S:,0010,"ABC"

// Set device name to be "ABC", where device

// name is stored in EEPROM starting from

// memory address 0x0010

CAUTION

Use caution when writing values to the EEPROM memory. Incorrect values can give

unexpected results. It is strongly recommended to contact Microchip Technical

Support before using this command.

S>,0

// Turn off command prompt

// Display basic settings
