When command “LS” has no parameter, it displays all server services along with
their characteristics. Command “LS” could optionally take one or two parameters. If
one parameter is given to command “LC”, it must be UUID of server service. Then
only the server service with input UUID along with all its characteristics will be
displayed. If two parameters are given to command “LS”, the first parameter is the
UUID of server service and the second parameter is UUID of its characteristic. Then
only the characteristic with given UUID in the server service with given UUID is
displayed.
Example: LS // Display all server services
3.3.3.4 CHR
According to command interpolation method described in section 3.3.3.1, command
“CHR” reads content of characteristic of client service from remote device by
addressing its handle.
The parameter of command “CHR” is 16-bit hex value of the handle, which
corresponds to a characteristic of client service. User should be able to find match
between handle and its characteristic UUID by command “LC”.
This command is only effective if an active link with peer exists, the handle
parameter is valid and the corresponding characteristic is readable according to its
property. The value returned is retrieved from remote peer device.
Example: CHR,001A // Read the content of characteristic with
// handle 0x001A from remote device
3.3.3.5 CHW
According to command interpolation method described in section 3.3.3.1, command
“CHW” writes content of characteristic in client service from remote device by
addressing its handle.
This command takes two parameters. The first parameter is 16-bit hex value of the
handle, which corresponds to a characteristic of client service. User should be able
to find match between handle and its characteristic UUID by command “LC”. The
second parameter is the content to be written to the characteristic. The format of
each public characteristic is defined in Bluetooth SIG specifications. User defines the
format of each private characteristic.
This command is only effective if an active link with peer exists, the handle
parameter is valid and the corresponding characteristic is writable according to its
