3.8.4 HANDLING OF RECEIVED DATA WHEN THE PRINTER GOES INTO POWER SAVE MODE
Data is left in the received buffer until reception is stopped and a timeout occurs (power save
mode) because the received buffer has not been initialized.
Channel 1
Channel 2
Re-connection is
enabled when the same
ESSID is assigned
.
The printer tries an active scanning as a joiner with ESSID:
ABC. When the printer receives a valid response from the
creator, it connects to the IBSS created by the creator.
If the printer cannot receive a valid response from
the creator after performing an active scanning as
a joiner with ESSID “ABC”, the printer itself
becomes a creator and creates an IBSS network.
At this time, the printer refers to its own setup data
for the channel to be used.
After that, moving this new network into the cell of BSSID:
X1 network may cause the BSSID to change to BSSID:
X1.
Note: It depends on the device type.
ESSID (Extended Service Set ID):
One of the identifiers,
identifying a name of a wireless access point. It is named by a
user.
BSSID (Basic Service Set ID):
One of the identifiers, identifying
a wireless network. In the case of IBSS networks, it is named by
the creator.
Note: Direct communication with wireless device is not allowed
when BSSID is different.
