Command Descriptions
Enter AT Command Mode
Prior to sending this command, the OEM Host must ensure that the transceiver’s RF transmit buffer is empty. If
the buffer is not empty, the radio will interpret the command as data and it will be sent over the RF. This can
be accomplished by waiting up to one second between the last packet and the AT command. RF packet size
must be set to minimum of 6 in order to send this command.
