Android Question Any Android ESP 32 libraries?

[seskindell]

Looking to connect directly a ESP 32 module to an Android phone using the NOW protocol.

What is the NOW protocol?

It is very simple to connect directly to ESP 32 modules with Bluetooth or wifi.

I think he talks about 'ESP-Now' which is a protocol initiated by Espressif

NOW maybe comes from 'NO-W ifi' as no router-based Wifi-Network is needed.

If it is not based on TCP/IP or UDP then you will not be able to use it with Android.

NOW protocol
This simplified protocol makes the connection much faster and thus also reduces the power consumption of the controller.
However, ESP-Now also has disadvantages, the amount of data per packet is limited to 250 bytes and the Internet can only be reached via a gateway.
