WL1807MOD: Parameter configuration for permanently disabling 5GHz channel

Ronny Ståhle
Prodigy 40 points
Part Number: WL1807MOD


Hi,

We are only using the 2.4GHz band and are using only one chip antenna (dual band; Pulse W3006) connected to the RF_ANT1 port on the IC. However, we have still detected Wifi traffic on the 5GHz Wifi band with good signal strength so it seems that the internal RF switches in the IC some times is set to take in traffix from the RF_ANT1 port to the 5GHz channel inside the IC.

This is not wanted since it causes instability/bugs "upstream" in the main application FW, and we have no intention of using the 5GHZ Wifi band in the final product.

Now, we suspect some sort of bug in the Texas FW/driver for the chip during recovery which maybe lead to automatic reconfiguration.

So first of all we wonder if it's enough to indicate in the config that we are only using one antenna by using the statement:

wl18xx.phy.number_of_assembled_ant5 = 0x00

, or is it needed to do some other configuration to be certain that the 5GHz channel is always disabled ?

Best regards

Ronny

    Hi Ronny, 

    You are correct in the config statement. That should be the parameter you need to turn off 5GHz. Recall to reconfigure the wl18xx-conf.bin as it is the output of the wlconf tool: 

    $ ./wlconf -i $binary_name -o $binary_name -s wl18xx.phy.number_of_assembled_ant5=$number_5G_antenna
