The theoretical specification is 150Mbps (18.75Mbit/s), and the measured maximum speed is up to 18.65Mbit/s.

The default AT firmware does not support this feature; firmware that enables web functionality and sets the port number to greater than 12 is required for parts involving embedded web pages.

After modifying the factory_param_data.csv file, delete the sdkconfig file and the build directory,

then recompile the AT firmware and flash it.

Currently, ESP-AT only supports BLE 4.2 specifications.

If you are powering the MS11SF11 module using a USB to TTL tool, it's possible that enabling BLE

broadcasting increases power consumption, and insufficient power supply may prevent a normal connection. It's advisable to consider using a different power source.

It's recommended to have up to 4 stable BLE connections.

The default BLE MTU size is 23 bytes, but it can be set to a maximum of 517 bytes.

When communicating with other devices, the MTU size is negotiated, and the final MTU selected is the smaller of the two endpoints.

Yes, it can. This functionality is implemented at the application layer, where BLE first collects data and then sends it out via Wi-Fi.
