Enter AT Command Mode
Prior to sending the “Enter AT Command Mode”
Command to the transceiver, the OEM Host must
ensure that the RF transmit buffer of the
transceiver is empty (if the buffer is not empty, the
”Enter AT Command Mode” Command will be
interpreted as packet data and transmitted out
over the RF).
waiting up to one second between the last
transmit packet and the AT Command. The Enter
AT Command mode command is as follows:
Exit AT Command Mode
To exit AT Command Mode, the OEM Host should
send the following command:
O
The AC4790 transceiver contains static memory that holds many of the parameters that control the transceiver operation.
Using the “CC” command set allows many of these parameters to be changed during system operation. Because the
memory these commands affect is static, when the transceiver is reset, these parameters will revert back to the settings
stored in the EEPROM. While in CC Command mode using pin 17 (Command/Data), the RF interface of the transceiver
is still active. Therefore, it can receive packets from remote transceivers while in CC Command mode and forward these
to the OEM Host.
While in CC Command mode using AT Commands, the RF interface of the transceiver is active, but packets sent from
other transceivers will not be received. The transceiver uses Interface Timeout/RF Packet Size to determine when a CC
Command is complete. Therefore, there should be no delay between each character as it is sent from the OEM Host to
the transceiver or the transceiver will not recognize the command. If the OEM Host has sent a CC Command to the
transceiver and an RF packet is received by the transceiver, the transceiver will send the CC Command response to the
OEM Host before sending the packet. However, if an RF packet is received before the Interface Timeout expires on a CC
Command, the transceiver will send the packet to the OEM Host before sending the CC Command response.
When an invalid command is sent, the radio scans the command to see if it has a valid command followed by bytes not
associated with the command, in which case the radio discards the invalid bytes and accepts the command. In all other
cases, the radio returns the first byte of the invalid command back to the user and discards the rest.
In order to send the Enter AT Command Mode command, the RF Packet Size must be set to a minimum of six.
