 ## Atmel/Microchip
 
-The ATILC3000 Bluetooth/Wifi combo controller has been used with Linux on embedded devices by Atmel/Microchip. Drivers and documentation are available from a [GitHub repository](https://github.com/atwilc3000). The ATWILC3000 has a basic HCI implementation stored in ROM and requires a firmware image to be uploaded before it can be used. Only the BLE Controller is currently qualified as [https://www.bluetooth.org/tpg/QLI_viewQDL.cfm?qid=36402](QDID 99659). Please note: the Bluetooth firmware is 270 kB.

It might need a separate Wifi firmware as well.
 
 **BD Addr** can be set with vendor-specific command although all chipsets have an official address stored. The BD_ADDR lookup results in "Newport Media Inc." which was [acquired by Atmel](http://www.atmel.com/about/news/release.aspx?reference=tcm:26-62532) in 2014.

 ## Toshiba
 
-The Toshiba TC35661 Dual-Mode chipset is available in three variants: standalone incl. binary Bluetooth stack, as a module with embedded stack or with a regular HCI interface. The HCI variant has the model number TC35661–007.

-We've tried their USB Evaluation Stick that contains an USB-to-UART adapter and the PAN1026 module that contains the TC35661 -501. We have been told by our distributor that the -501 variant also supports the HCI interface. However, while our tests have shown that Classic Bluetooth with SPP works fine with this variant, none of the LE commands work.
+We first tried their USB Evaluation Stick that contains an USB-to-UART adapter and the PAN1026 module that contains the TC35661 -501. While it does support the HCI interface and Bluetooth Classic operations worked as expected, LE HCI Commands are not supported. With the -007 and the -009 models, everything works as expected.
 
 **SCO data** might work. We didn't try.
