Description
The ESP8266 ESP-01S is an inexpensive 802.11IEEE 802.11 is a set of protocol standards that define communication for a Wireless Local Area Network (WLAN). In order for WiFi to work between different devices, they all need to agree on how they are going to communicate. The current version of the standard is IEEE 802.11-2007, with many amendments such as 802.11a, 802.11b, 802.11g, and 802.11n.b/g/n 2.4GHz WiFi module with an integrated TCP/IPTCP/IP is a suite of internet communication protocols. TCP (Transmission Control Protocol) is responsible for establishing reliable, ordered data delivery, and handling congestion control, while IP (Internet Protocol) focuses on routing packets of data to their destination. protocol stack that can give a microcontroller access to your WiFi network. The ESP-01S module contains an ESP8266EX SoCSystem On a Chip (Datasheet), 1MB flash memory chip, RFRadio Frequency circuitry, and built in PCBPrinted Circuit Board trace antenna (MIFAMeandered Inverted-F Antenna) on a miniature development board the size of 24.8mm x 14.3mm (0.98in x 0.56in). The board also has one blue LEDLight Emitting Diode that flashes temporarily when power is applied and flashes when there is serial activity.
The ESP-01S can be programmed through its (RXReceive, TXTransmit) pins using a USB Serial Adapter (USB-to-TTL converter), a microcontroller with USB serial, or a dedicated ESP-01S USB Programmer. The firmware can be LuaLua (meaning moon) is a lightweight, high-level, multi-paradigm, open source programming language built on top of the C programming language and designed primarily for embedded use in applications. code, Arduino code, MicroPython code, or programmed directly through ATShort text string commands where the AT stands for ATtention and every command line starts with "AT" or "at". commands. The ESP-01S module has three WiFi modes it can operate in: APA WiFi Access Point (AP) is a device that creates a wireless local area network, or WLAN, and acts as a central hub that allows other devices, such as smartphones or computers, to connect to it over WiFi., STAA WiFi Station (STA) is a device that has the capability to connect to an existing WiFi network as a client in the same way other devices, such as smartphones or computers, join an established network and communicate with other devices on that network or access the internet., or AP+STAA WiFi device in AP+STA mode acts as both an Access Point (AP) as well as a Station (STA), where the device can connect to an existing network as a client (STA) while simultaneously hosting its own network (AP) for other devices to connect to..
The board operates on 3.3V power and logic, so a voltage converter will be necessary when connecting to 5V devices. The power consumption is about 100mA on average for continuous transmission, but can spike up to 300mA. There are low power modes for battery operation, such as modem sleep (20mA), light sleep (2mA), and deep sleep (0.02mA).
The ESP-01S was intended as an upgrade to the ESP-01 with the following changes:
- ESP-01S has an antenna redesign providing slightly better signal strength and range
- ESP-01 has 512kB flash memory and ESP-01S has 1MB/4MB flash memory
- ESP-01 has two LEDLight Emitting Diodes: a red power indicator and blue serial transmitter indicator. The ESP-01S has only one blue LED that flashes temporarily when power is applied and flashes when there is serial activity.
- There are 3 new on-board pull-up resistors on the ESP-01S module that provide a logic HIGH to pins RST, GPIO0, and CH_PD

WEP was ratified as a Wi-Fi security standard in September of 1999./TKIPTemporal Key Integrity Protocol (TKIP) is a security protocol used in the IEEE 802.11 wireless networking standard. It was designed as an interim solution to replace WEP without requiring the replacement of legacy hardware. TKIP employs a per-packet key system that was more secure than the fixed key system used by WEP. However, TKIP itself is no longer considered secure and was deprecated in the 2012 revision of the 802.11 standard. It was superseded by Advanced Encryption Standard (AES)./AESAdvanced Encryption Standard (AES) is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. It was developed an alternative to the Data Encryption Standard (DES), which was starting to become vulnerable to brute-force attacks. |
