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.

You can refer to the example here: https://github.com/espressif/esp-idf/tree/release/v4.0/examples/bluetooth/esp_ble_mesh/ble_mesh_wifi_coexist

Depending on the actual situation, it is possible to configure the module to operate in modes such as Modem-sleep, light-sleep, or deep-sleep within a certain working range, which is beneficial for reducing power consumption.

1. Is the hardware functioning correctly and connected properly? 2. Is the UART port of the Wi-Fi module connected consistently? 3. Have you included carriage return and newline characters when sending commands from the serial assistant?

2.4GHz: Longer transmission distance, lower speed compared to 5GHz, but more susceptible to interference.

5GHz: Shorter transmission distance, faster speed compared to 2.4GHz, but less susceptible to interference and more stable.

Wi-Fi 4: Supports the 2.4GHz and 5GHz frequency bands.

Wi-Fi 5: Operates in the 5GHz frequency band.

Wi-Fi 6: Operates in the 2.4GHz and 5.8GHz frequency ban
