Classic Bluetooth: BT Low Power Bluetooth: BLE
No, it doesn't. Our hardwares don't design two pins with Antenna.
AT firmware does not support Ble mesh and WiFi mesh for now. The users can develop this function by themselves using ESP-MDF framework.
Yes, it does. The MS11SF11 module adopts ESP32C3 chipset.
It supports multiple of WiFi-enabled modules, such as ESP32, ESP32-C and ESP32-S series Socs, which can be used to develop Matter WiFi terminal devices.
The module MS11SF1 has BLE (low power Bluetooth) function and the Bluetooth version is: BLE5
It supports a great variety of networking modes: BluFi networking (Bluetooth networking),
AP networking, Smartconfig networking, Web networking,etc.
It adopts the LEXIN ESP32-C3FN4 chip solution.
WiFi module MS11SF1 has built-in 4M SPI Flash, 400KB SRAM, currently only one module.
If the storage space is not enough to use the SPI interface to expand the storage, the maximum support 16M.
