Subject: [PATCH 1/3] wifi: wcn36xx: add support for WCN3610
Date: Wed, 4 Mar 2026 13:24:07 -0600 [thread overview]
Message-ID: <20260304192409.927562-1-kerigancreighton@gmail.com> (raw)
The WCN3610 is a 2.4GHz-only WLAN/BLE combo chip used in some
cheaper Android and Windows phones such as the Lumia 550, and
IoT devices like the Anki Vector robot. It shares a lot in
common with the WCN3620.
Tested on an Anki Vector 1.0 and 2.0 robot. Support for other
WCN36xx chips has not been affected.
The WCN3610 requires specific BTC configuration values for
stable Wi-Fi. Without these values, there's some packet loss.
An extra CFG table was made so other chips are not affected.
STA_POWERSAVE causes firmware bugs (long hangs) with the
WCN3610, thus it has been disabled just for this chip.
