3. Operational Description
-SIGFOX
SIGFOX able to transmit and receive messages using the SIGFOX network.
This module address the RC1(Europe), RC2(North America), RC3(Japan), RC4(Australia, new Zealand),
RC5(Korea).
This module is used by receiving a sigfox beacon-signal from base station and changing to the frequency used
in that country.
-BLE
Bluetooth 4.2 optimized for low-power applications.
The RADIO contains a 2.4 GHz radio receiver and a 2.4 GHz radio transmitter that is compatible with
Nordic's proprietary 1 Mbps radio modes in addition to 1 Mbps Bluetooth® low energy mode.
-WIFI
ESP8285 implements TCP/IP, the full 802.11 b/g/n/e/i WLAN MAC protocol and Wi-Fi 2.4GHz.
Direct specification. It supports not only basic service set (BSS) operations under the distributed control function
(DCF) but also P2P group operation compliant with the latest Wi-Fi P2P protocol. Low level protocol functions
are handled automatically by ESP8285.
• RTS/CTS
• acknowledgement
• fragmentation and defragmentation
• aggregation
• frame encapsulation (802.11h/RFC 1042)
• automatic beacon monitoring / scanning, and
• P2P Wi-Fi direct
Passive or active scanning, as well as P2P discovery procedure is performed autonomously once initiated by
the appropriate command. Power management is handled with minimum interaction with host to minimize active
duty period.
-GPS (GLONASS)
The application use GPS(GLONASS) to determine location. It will then transmit the location information via
SIGFOX. It also will transmit other information like temperature, accelerometer, and so on.
-NFC
Type 2 near field communication (NFC-A) tag with wakeup-on-field and touchto-pair capabilities
