This ensures that the Bluetooth requirements for ACP and those defined by the FCC and ETSI are satisfied over the operating temperature rang of -5℃℃℃℃to +45℃℃℃℃. Although the design is capable of generating in excess of +18dBm, regulatory compliance over the full temperature range of -5℃℃℃℃ to +45℃℃℃℃ will not be satisfied if the transmit power approaches this value.

This command display the local device BD address Modifiers Description B (Display local BD address) B? Inquire the Local BD address This command enable or disable flow control signals (CTS/RTS) of the COM port. Note, the setting is not affected by ATZ0 but will cause a reboot Modifiers Description C (Flow Control) C0 Disable flow control.
C1 (Default) Enable flow control. C? Inquire the current setting For security purpose, We can specifies the unique remote device can be connected. In master role, it automatically inquire and search the slave even the slave is undiscoverable. In slave role, the command should be as a filter condition to accept the master’s inquiry. Modifiers Description D=xxxxxxxx "xxxxxxxx" is a string of 12 hexadecimal digits. D0 (Default) Clear Remote BD address setting, inquire any slave in master mode or accept any master in slave mode. D (Set Remote BD address) D? Inquire the Remote BD address setting This command specifies whether the device should echo characters received from the UART back to the Host Modifiers Description E0 Characters received from the UART are not echoed back to the Host E1 (Default) Characters received from the UART are echoed back to the Host. E (Local Echo) E? Inquire the current setting This command is used to find any bluetooth device in neighborhood within 60 seconds timeout. If any device is found, its name and address will be listed.

Inquire the device name This command is used to enable/disable auto-connection feature in master role. By the way, it is used to online switch from command mode to data mode. Note, it will cause a reboot when ATO0 or ATO1 take effect. Modifiers Description O Online switch from command mode to data mode O0 (Default) Automatically connectting to a device which is assigned in “ATD” or any available device if “ATD” was not assigned. O1 Disable auto-connection feature, user should manually use “ATA” command to connect a remote device. O (Auto connect setting) O? Inquire the current setting This command specifies the PIN number. It control to off the PIN code authorization that allow to establish a connection without PIN code. Default PIN number is "1234" Modifiers Description P (Set PIN code) P=xxxx (Default) "xxxx" is 4~8 digit string
P0 Turn off the PIN code authorization P? Inquire the current PIN number The command is used to determine if result Codes should be sent to the Host. When result Codes are supressed, the device does not generate any characters in response to the completion of a command or when an event occurs. Four Result Codes : OK,CONNECT,DISCONNECT,ERROR Modifiers Description Q0 (Default) The device will prompt Result Codes Q1 The device will not prompt Result Codes Q (Result Code Supression) Q? Inquire the current setting This command specifies whether the device could be master or slave device. If change the role, the adaptor will reboot and clear all paired addresses. Modifiers Description R0 The device as master role. R1 (Default) The device as slave role. R (Set Role) R? Inquire the current setting This command is used to disable/enable escape sequence “+++”. Modifiers Description X0 Disable escape character check. X1 (Default) Enable escape character check. X (Escape Control) X? Inquire the current setting This command is used to restore default setting and reboot Modifiers Description Z (Restore) Z0 Restore the default setting The factory settings of UART are as follows:  Baud rate: 19200 bps  Data bit: 8  Parity: none  Stop bit: 1  Flow control: H/W or none
