5.2.1 AP
<Serial Interfacing> The AP command is used to enable the RF module to operate using a
frame-based API instead of using the default Transparent (UART) mode.
Command
ATAP (
API Enable
)
Range
0-1
Default Value
0
Parameter
Value
0: Disabled (Transparent operation)
1: API enabled
Effective Conditions
Validate at once after the command
Minimum Firmware Version Required
：

The examples for changing the working mode:
Input 3-character command sequence
“
+++
”
and switch to the AT Command mode.
Using ATAP command to setup the working mode you want, such as ATAP 0<CR> or ATAP
1<CR>.
If the setting is still needed to be validated after restart the module next time, using ATWR<CR>
command to write the setting into Non-volatile memory.
Input
“
ATCN<CR> command to exit from AT Command mode, the module will enter the setting
working mode.
5.2.2 BD
<Serial Interfacing> The BD command is used to set and read the serial interface data rate used
between the RF module and host. When parameters 1-7 are sent to the module, the respective
interface data rates are used (as shown in the table on the below). The RF data rate is not affected by
the BD parameter (it is fixed to 250kbps). We recommend that users don
’
t select too low interface
data rate, or it will cause the serial port data communication overflow. We only offer the AT
command to change the serial port data rate, no command for changing data rate under API mode.
Command
ATBD
(Interface Data Rate)
Range
1-7
