[08:56] schestowitzOn 8th December 2020, the other shoe dropped: the project known as Community Enterprise Operating System (CentOS, and I pronounce it as cen-tos, ypmv), which has been under the Red Hat technology ecosystem, got redefined as CentOS Stream and also where in the ecosystem CentOS Stream would fit.
[08:59] schestowitzGiven the success of working with the Yun, I figured that the work is done. But no! I wanted to further optimise the setup as the Yun should really be a prototyping board rather than a deployed in production board mainly because, in my case, I only need two sensors that need to be accessed and the Yun has lots of other pins for a larger project.
[08:59] schestowitzAnd I did have in my possession a bunch of ESP8266-01 boards (ESP-01 in short), whch has a built in wifi capability, and can be programmed just as one would the Arduino. And these boards have two input pins that I could use and so, my attention shifted to making the ESP-01 do what the Yun was doing.
[08:59] schestowitzThe ESP-01 is designed with some use case considerations: a) it can only handle 3.3v as the input b) the board can be flashed via shorting to ground of one pin and has to be done manually. These constraints or considerations, I am sure, is the reason why these boards are about S$1.50 or so. So to program the ESP-01, you will need a 3.3v supply and a way to get to the USB port of you laptop and that is all ● Dec 15 [09:00] schestowitz done via a USB UART similar to this.
