Will WL18xx work on ad-hoc mode?

Other Parts Discussed in Thread: WL1835MOD

Hi There,

Tried ad-hoc mode on WL18xx (BBB + WL1835MOD) with basically the following:

$ iwconfig wlan0 mode ad-hoc

$ iwconfig wlan0

wlan0 IEEE 802.11abgn ESSID:off/any

Mode:Ad-Hoc Cell: Not-Associated Tx-Power=0 dBm

Retry long limit:7 RTS thr:off Fragment thr:off

Encryption key:off

Power Management:on

$ iwconfig wlan0 essid 'my-adhoc'

$ iwconfig wlan0

wlan0 IEEE 802.11abgn ESSID:"my-adhoc"

Mode:Ad-Hoc Frequency:2.412 GHz Cell: Not-Associated

Tx-Power=0 dBm

Retry long limit:7 RTS thr:off Fragment thr:off

Encryption key:off

Power Management:on

$ ifconfig wlan0 192.168.0.1 up

[78005.641464] wlcore: ERROR command execute failure 14

ifconfig: SIOCSIFFLAGS: Input/output error

The ad-hoc mode is required to have mesh routing protocol like OLSR daemon on layer 3. Will TI support ad-hoc (ibss) mode in the near future? If NOT, wonder if TI can tell us the names of vendors having the chip that do support the mode.

By the way, the P2P mode does not meet the requirements of our application.

Thanks.

Hi Simon,

Ad-Hoc is not supported, and no plan to support it either.

Hi Gigi
What is the reason that it is not supported ( Hardware, Firmware, Driver, Application Software ....)

Thanks

Hi,

It's been replaced by WiFi-Direct.

So, does WiFi Direct offer a similar mode? If not, your offering doesn't support alternatives- your mesh mode is woefully inadequate on numerous fronts.

If I can't do Mesh with more than about 32 nodes and I can't do AdHoc...what USE is your product, even for IoT?

www.thinktube.com/.../wifi-direct WiFi Direct is NOT a replacement for Adhoc- and you can't use your parts for any real uses. I figured out why the 10 limit- you mention that AP mode is limited to 10 as well in hardware. You're leveraging the hardware. You should be doing a SoftMAC if possible for this stuff- because, quite simply, except for a mobile phone or jetpack access point, this chipset isn't overly useful. (And you shouldn't be up-selling it for things that it CAN'T do right...like mesh networking...because your device lacks crucial functionality (10 device limitation for nearby first-hop, no adhoc))
