This change adds support for the USB Transport Layer as described in the bluetooth spec. Isochronous endpoints are not yet supported. Because of limitations in the NuttX bluetooth stack, only one USB device can be used. This driver will only allow one USB dongle to use bluetooth. A Laird USB BT4.2 dongle (from Mouser) was used for testing: M/N BT851 1.0 1829, FCC ID:SQGBT850 lsusb: 04b4:f901 Cypress Semiconductor Corp. CYW20704A2 The following commands were used to test from the nsh prompt: bt bnep0 scan start bt bnep0 scan stop bt bnep0 scan get bt bnep0 info The Linux gatttool was used to connect over wireless. With the BDAddr found by "bt bnep0 info", start gatttool using: gatttool -b BDAddr -I Connect to the device using: connect Read the device name using the GAP device name UUID: char-read-uuid 2a00 Part of the response is: value: 41 70 61 63 68 65 20 4e 75 74 74 58 which is the string "Apache NuttX"
Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
