  • Forum Post: Re: Wi-Fi Ad-hoc network using WL1271

    Nestor49613
    Thank you very much for the answer Sinoj. Do you know if it is possible to request a specific security (eg. WEP, WPA) to be used for the created Ad-hoc network and to specify the key/passphrase to be used for accessing that ad-hoc network? Best regards, Nestor

    Nestor49613
    Hi all, I'm trying to find out if there is ad-hoc Wi-Fi network support in WL1271. I can see that there is an option to connect to an existing ad-hoc network in the CLI application. However I couldn't find a way to create an ad-hoc network that other WL1271 chips would connect to. Could...

    Matt Kurtz
    Dhanesh, We do not have a WLAN driver for uC/OS-II. If you want to try and make it work on your own, there is a Linux WLAN driver for 1271 using the mac80211 open source kernel solution. The driver is called wl12xx and it is maintained as part of the linux-wireless community. Here is a basic wiki...

    Saurabh Narang
    Tracking scan has minimum dwell time set to 500msec and discovery and immediate scan have minimum dwell time set to 1sec. WiFi device stays on that scan channel for at least that duration . This is the reason why you noticed 500mse delay in channel switch in normal scenario and 1 sec delay when AP count...

    Alon Srednizki
    Hi, If you would like to use a fixed rate, then yes, you need to set it as a basic rate too. I wouldn't say that it's a specification of WL1271 per say, but a general behavior of 802.11. Thanks, Alon.S

    Alon Srednizki
    Hi Noah, TxPower may differ from 11b, 11g & 11a. In general our solution supports 11d which handles the power limits per country (country, channel, band). If you are working with AP that doesn't support 11d then as a station you don't have to support all this restrictions (we are a passive...

    Hi Sivaram, RSSI max value is indeed limited by SW to -45 (the HW has no issues receving stronger packets). I'm not sure to what percentage table you are referring to. However, since our RF sensitivity is -89dBm a possible conversion for GUI perspective can be between -45 (100%) to -89(0%)...
