README ====== Spresense is a compact development board based on Sony’s 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. Refer to https://developer.sony.com/develop/spresense/ for further information about this board. NOTICE: To run the nuttx, bootloader for Spresense SDK 2.1.0 or later must be installed. 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. 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.
