I am trying to send a command to a WiFi module connected to a microcontroller. Can I send the data without the help of a server? My phone and the WiFi module both are in the same local network.

yes you can if the microcontroller is running a server.

Is there a method to send commands to my microcontroller while in the same local network, without any server?

What is the microcontroller, Arduino? Raspberry Pi? A Pi can easily run a server, Arduino I do not know. Usually people use Bluetooth with it, and in this case App Inventor can act as server or client.

Cheers, Ghica.

It is neither Arduino nor Pi. It is MSP430. I connected a Wi-Fi module to it. So it is connected to my router. I have to send commands to it from my app while on the same local network. How can I do that?

I think you will have to ask in an msp430 dicussion group. From AI you can send messages via Wifi to something that acts as a web server, or you can use the built-in Bluetooth component. So, if you can find out how this controller can communicate via wifi, we can help to use this protocol in AI.

I have a Wi-Fi module connected to the microcontroller. The Wi-Fi module takes in the commands and forwards those commands to the microcontroller by a serial port. That is done. I am not able to figure out how to send commands over Wi-Fi. Can I send the commands as text directly to the IP of the device without a web server?

Thanks, Saket

So, the Wifi module is a webserver in itself? Otherwise it is not possible. Really, this is not an AI problem. AI can act as a webclient, and send requests to a webserver. This is the way HTTP works, always client to server. So, maybe it is possible, but you have to find out yourself, by looking at what the microcontroller can do.
