C O M M A N D D E S C R I P T I O N S
E n t e r AT C o m ma n d M o d e
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.
Note: RF Packet Size must be set to a minimum of six to use this
command.
E x it A T C o m m an d M o d e
The OEM Host should send this command to exit AT Command mode
and resume normal operation.
S t a t u s R eq u e st
The OEM Host issues this command to request the status of the
transceiver.
C h a n g e C h a n n e l
The OEM Host issues this command to change the channel of the
transceiver.
C ha n g e S er ve r / C li en t
The OEM Host issues this command to change the mode of the
transceiver from Server to Client and vice versa.
