MS11SF1-ESP32C3 Support 2.4G Wi-Fi4 （IEEE802.11 b/g/n） , support AP/STA/AP +STA Mode, Tiny size
Key features
MS11SF1 is a WIFI + BLE Soc combo module that supports WIFI 4 as well as BLE 5.0. This module supports Wi-Fi4 + BLE 5.0, equipped with RISC-V 32-bit single-core processor, the operating frequency up to 160MHz. MS11SF1 supports the use of AT commands to development, through the serial port to send AT commands to configure the Wi-Fi, BLE, to achieve the function of pass-through.BLE single packet can support up to 514 bytes to be sent, the chip wakes up BLE and BLE and WIFI start at the same time when the chip wakes up, WIFI is STA mode by default and BLE is broadcast mode.
MS11SF1
This firmware includes BLE slave transponder, WIFI can be setted as AP or STA mode for data transfer. WIFI can be connect- ed to a variety of cloud servers, such as Ali Cloud, Baidu Cloud, Amazon cloud, etc.. BLE and WiFi can be started at the same time, but when transmitting data, BLE has to exit instruction mode because of transmission through, and WIFI data transmis- sion is through instruction control, so BLE and WiFi can not be carried out at the same time, data transmission.
In order to ensure the normal operation of the module, the module needs to provide a stable 3.3 V voltage, CHIP-EN pin pull up, the module will be awakened, into the BLE broadcast state and serial port will be opened. WIFI is not started, needs to be configured with instructions to start.
In the instruction mode, the basic parameters of the module, BLE parameter and WIFI parameter can be configured by AT instruction. See the MS11SF1-AT command set file for details.
