D1 (Retired) UNO size ESP-12 firmware rev?
Posted: Thu Oct 27, 2016 4:40 pmI have these 2 older D1 R1 (Retired) UNO-size boards that do not behave the same, and I need to figure out if they have at least the same firmware version.
Is there a simple way to figure out the on-board ESP-12 firmware via Arduino IDE?
edit: answering myself... ESP has just a bootloader inside so it really doesn't matter what's loaded afterwards as long as it loads without error. So if my sketch compiles and loads via Arduino IDE, and one wemos D1 R1 performs ok while the other doesn't may point to some hardware problem with one of them.
Now, bootloader version is irrelevant I hope?
