I have a few of these modules and want to use them as wifi connection for my Seeeduino XIAO, to get a tiny sensor platform. At the moment I don’t know how to make a antenna for them. My planned use is to use it indoors to monitor all rooms with a BME280. In my apartment the furthest sensor node is about 10m (30ft) from my centrally located router, some nodes need to communicate through one concrete wall. What is the simplest way to meet those requirements?
Air602 needs some development and is not friendly to Arduino support.You can go to the website of original factory to see relevant data.
