In the meantime, JT was busy with trying the boards work. We experienced great difficulties, as the firmware we were using on the prototype boards did not work on the produced PCBs. After a lot of effort, we understood that there is a difference in the ESP modules used. The prototype has module ESP8266 12s with 4MB of memory and the boards have ESP8266 07 with 1MB of memory.
This means that JT had to do some refactoring to make sure the compiled firmware is less than 0,5MB.
Luckily enough, JT is a genius and he managed to do it and we have the very first RMLD board working 🙂
It works nicely with our prototype application made in APP INVENTOR, so I am able to manage the LED lights
Today JT discovered that there is a HTTPS server implementation for ESP32, but there is none for ESP8266. This leads us to thoughts about upgrading the chip in the next HW revision.
