AT+GATTCHAR

Gets or sets the value of the specified custom GATT characteristic (based on the index ID

returned when the characteristic was added to the system via AT+GATTADDCHAR).

Codebase Revision: 0.3.0

Parameters: This function takes one or two comma-separated functions (one parameter =

read, two parameters = write).

The first parameter is the characteristic index value, as returned from the

AT+GATTADDCHAR function. This parameter is always required, and if no second

parameter is entered the current value of this characteristic will be returned.

The second (optional) parameter is the new value to assign to this characteristic (within

the MIN_SIZE and MAX_SIZE limits defined when creating it).

Response: If the command is used in read mode (only the characteristic index is provided as

a value), the response will display the current value of the characteristics. If the command is

used in write mode (two comma-separated values are provided), the characteristics will be

updated to use the provided value.
