AC4486 Specifications
4.4.3 EEPROM Exit Configuration Mode Command
The OEM Host can cause the transceiver to exit Configuration Mode by issuing the Exit Configuration
Mode command to the transceiver. However, the transceiver will not reflect any of the changes
programmed into the EEPROM until the transceiver is reset.
Host Command:
Transceiver Response:
4.5 AC4486 AT C
The AT Command mode implemented in AC4486 firmware version 3.2 and higher creates a virtual
version of the Command/Data line. The Enter AT Command mode command asserts this virtual line
Low (to signify Command mode) and the Exit AT Command mode command asserts this virtual line
High (to signify Data mode). Once this line has been asserted Low, all on-the-fly CC Commands
documented in the manual are supported.
When in AT Command mode, the transceiver will maintain synchronization with the network, but RF
packets will not be received. However, an ambiguity of approximately 10ms exists where, if the Enter
AT Command mode command has been sent to the transceiver at the same time an RF packet is
being received, the RF packet could be sent to the OEM Host before the Enter AT Command mode
command response is sent to the host.
4.5.1 Enter AT Command Mode
Prior to sending the Enter AT Command mode command to the transceiver, the 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). This can be
accomplished by waiting up to one second between the last transmit packet and the AT Command.
The host must also ensure that the Fixed Packet Length for the transceiver is set to a minimum of six.
The Enter AT Command Mode command is as follows:
