I want to develop a product to make Wi-Fi to connect PC <-> MCU <-> MCU. I started looking for Wi-Fi modules with the stack that I need already implemented and some kind of AT commands interface in order to configure it, but those are a bit expensive.
Next idea it's to use a 2.4Ghz transceiver and a MCU with the stacks implemented. That will be a lot cheaper, but I don't know where to start.
My goal it's too have this module connected to something (an analog sensor, a remote UART, whatever) and, by sending a command over my PC or another MCU, get the data present in the sensor.
Could ypu help me through the first steps? I'm worried about the stack to choose.
I don't know if I can do this here, but I've found Carambola a few months ago and right now they have an even cheaper module, the Carambola 2, I guess that it's a good module for projects that require Wi-Fi.
