README
======

Spresense is a compact development board based on Sonys power-efficient
multicore microcontroller CXD5602. It allows developers to create IoT
applications in a very short time and is supported by the Arduino IDE as well
as the more advanced NuttX based SDK.

- Integrated GPS
  The embedded GNSS with support for GPS, QZSS and GLONASS enables applications
  where tracking is required.
- Hi-res audio output and multi mic inputs
  Advanced 192kHz/24 bit audio codec and amplifier for audio output, and
  support for up to 8 mic input channels.
- Multicore microcontroller
  Spresense is powered by Sony's CXD5602 microcontroller (ARM® Cortex®-M4F × 6
  cores), with a clock speed of 156 MHz.

about this board.

Configuration sub-directories
-----------------------------

  elf

    This is a configuration to test apps/examples/elf.

  module

    This is a configuration to test apps/examples/module.

  posix_spawn

    This is a configuration to test apps/examples/posix_spawn.

  smp

    This is a configuration to run Spresense in SMP mode. To use this
    configuration, bootloader for Spresense SDK 1.5.0 or later must be
    installed.

  wifi

    This is a configuration for Spresense + Wi-Fi addon (Telit GS2200M) module.
    With this configuration, (1) you can connect Spresense to an existing Wi-Fi
    access point (2.4GHz 802.11b/g/n are supported) or (2) you can make
    Spresense as a Wi-Fi access point. In both cases, you can login to the
    Spresense with telnet, also access to a webserver (NOTE: this case you need
    an extension board with microSDHC card)

    (1) Station (STA) mode

    To run the module in Station mode (i.e. to connect to an existing Wi-Fi
    access point), You need to specify SSID with passcode.

      nsh> gs2200m ssid-to-connect passcode &

    If the connection succeeded, IP address is statically assigned.

      nsh> ifconfig
      wlan0   Link encap:Ethernet HWaddr 3c:95:09:00:69:92 at UP
      inet    addr:10.0.0.2 DRaddr:10.0.0.1 Mask:255.255.255.0

    Then, you can run DHCP client (renew command) to obtain IP address as well
    as DNS server information. (NOTE: In current configuration, DHCP client on
    GS2200M is disabled. If you enable the internal DHCP client, you can not
    use DNS client on NuttX)

      nsh> renew wlan0 &
      renew [6:100]
      nsh> ifconfig
      wlan0   Link encap:Ethernet HWaddr 3c:95:09:00:69:92 at UP
      inet    addr:192.168.1.101 DRaddr:192.168.1.1 Mask:255.255.255.0

    Now, you can run telnetd and webserver on Spresense.

      nsh> telnetd &
      telnetd [7:100]
      nsh> webserver &
      webserver [9:100]
      nsh> Starting webserver

    Also, you can run NTP client to adjust the RTC on Spresense. (NOTE: we
    assume your network can access to pool.ntp.org, otherwise, you can specify
    CONFIG_NETUTILS_NTPCLIENT_SERVER)

      nsh> date
      Jan 01 00:00:36 1970
      nsh> ntpcstart
      Started the NTP daemon as PID=11
      nsh> date
      Jul 30 06:42:13 2019

    (2) Access Point (AP) mode

    To run the module in AP mode, you need to specify SSID to advertise and
    WPA2-PSK passphrase or WEP-key. (NOTE: in AP mode, you can also specify
    channel number to use. Also, you need to set CONFIG_WL_GS2200M_ENABLE_WEP=y
    if you want to use WEP instead of WPA2-PSK)

      nsh> gs2200m -a ssid-to-advertise 8-to-63-wpa2-psk-passphrase &
      or
      nsh> gs2200m -a ssid-to-advertise 10-hex-digits-wep-key &

    If the module was initialized in AP mode, you can see a new IP address is
    assigned.

      nsh> ifconfig
      wlan0   Link encap:Ethernet HWaddr 3c:95:09:00:69:93 at UP
      inet    addr:192.168.11.1 DRaddr:192.168.11.1 Mask:255.255.255.0

    Now you can connect your PC to the AP with the above SSID and WPA2-PSK
    passphrase or WEP-key which you specified.
