The Arduino Pro Mini kits I received recently from China aren't quite
okay. I had some strange troubles with them, and I am not quite sure
what was the reason. Yeah, I managed to connect the programming cable
backwards to one of them, and the Arduino started misbehaving. Uploads
did not finish unless I disconnected power and yanked the USB/UART
adapter and so on... On a second kit, I actually noticed I've used wrong
COM port, which would explain the connection timeouts :)
Anyway, I
reflashed all three of them with the bootloader from Arduino 1.0.5 and
they seem to work fine so far. The fourth one has already a new
bootloader as it was modded for 8MHz lowe power operation (crystal
implant and LED and LDO removal).
I spent the rest of the evening
looking for the right version of ESP8266 firmware, and working Arduino
library. So far, I'll stick with 0.9.2.4 I found under name v0.9.2.4 AT Firmware-ESPFIX.bin
As
for the library - after a lot of experiments, it looks like Lady Ada
got it right again. Her library works as expected (so far), uses
SoftSerial to communicate with ESP8266 (necessary when you use Arduino
with just one HW serial port), and compiles at first try! Thanks, that
was what I needed:
Adafruit ESP8266 library
Enough of HW stuff, going to play WoT...
