Wifi Support #32

Open Fishwaldo opened 1 year ago

Fishwaldo commented 1 year ago

Pending release of blobs or documentation from bouffalo.
See https://github.com/bouffalolab/bl_mcu_sdk/issues/85

MartinEssink commented 1 year ago

The SDK has been updated and from a quick glance seems to include blobs. https://github.com/bouffalolab/bouffalo_sdk/tree/e6e8da79a50aeb4fcb67ac380c3bd8885cd56faf/components/wireless

@MartinEssink that blobs are only for BL61X

WestonSkeans commented 10 months ago

The official bl808 linux has recently added wifi support: https://github.com/bouffalolab/bl808_linux

Via this project: https://github.com/bouffalolab/blwnet_xram

Maybe this can be used to expedite the effort to get Wifi support in OpenBouffalo?

gamelaster commented 10 months ago

@WestonSkeans someone tried it and it works OK, it is just not implemented into openbouffalo's buildroot image.

WestonSkeans commented 10 months ago

Wifi support (at least as described in the bl docs) doesn't appear to be implemented in the latest Release image of openbouffalo.

How can I make an image with https://github.com/bouffalolab/blwnet_xram included?

gamelaster commented 7 months ago

@DMBCT current branch already supports blwnet_xram

I can confirm after building HEAD and flashing the firmware from output/images along with the sdcard.img, wifi works correctly. I am able to scan for a 2.4GHz wifi network with WPA2-PSK security, connect to it, get an IPv4 address with udhcpc, and ping github.com:

There is some packet loss sometimes, but it is minimal.

So, if I understand correctly, they released the Wifi source code as open source?

I am trying to build the wifi driver on a separately cross compiled 6.2.0 kernel, but I am getting such errors when tring to install the module. Can anyone help me compile it in a right way?

I managed to install this driver by just building buildroot from scratch, but when trying to connect to my network I'm getting error -1

# blctl wifi_scan
# blctl wifi_scan_results
# blctl connect_ap myssid mypassw
error: ret -1

This is the dmesg part, where the driver was failed to register

Sorry for bothering you guys, I just forgot to flash a proper firmware image, now it's working like intended
