Hi all,
I am using Ameba RTL8195 modules. 1 module connects to sensors to get measurements in an outdoor environment. I want to get these readings to another module connected to PC. Is there any guidance available to connect these modules. Datasheet is available below:

I want to get these readings to another module
How? SPI? I2C? Serial? Servos waving semaphore flags? RF?
Serial
sal_murd:
Serial
What is the problem, then?
I want to establish peer to peer communication between these 2 ameba devices, whereby, the one in the outdoor environment sends the measurements to the one indoor connected to the PC via usb. What is the way forward please ?
What is the way forward please ?
You've already defined that - serial. Incorrectly, in my opinion. Sending data over wires, from outdoors to indoors, hardly makes sense.
In any case, I don't understand what the problem is. If you ARE going to use Serial, you connect the TX pin of one device to the RX pin of the other, and you connect the grounds, and you use Serial.print(), Serial.println(), or Serial.write() to send the data, and Serial.available() and Serial.read() to get the data.
I apologise for not describing well the problem. I want to transmit the measurements wireless to indoor device be it any method. Then the indoor connected device's serial monitor should be able to display all those measurements taken outdoor.
If those ARE WiFo devices, wouldn't it be simpler to make one a server (the indoor one) and one a client? Then, the client just makes a GET request with the data, and the server handles the GET request.
I don't see the relationship between those things and Arduino.
Im trying to make one Ameba as server, but getting an error message.

You need to take this up with the (I'm trying to use a politically correct term here, but really don't want to) at ameba. There is NO excuse for them building a class with the same name as the Arduino-provided WiFi library, when it operates on different hardware.
Is it possible to rename the library so that there is no conflict ? whats the way forward?
