Today i tried the the OTA with Blynk Air. I created the bin file then in Blynk air attached the file but i get this error message
“Firmware version mismatch”.
I have only 1 device.
Anybody know what exactly this means?
You will have a line in hour original sketch, currently running on the device, that looks something like this:
#define BLYNK_FIRMWARE_VERSION "0.1.0"
Your new sketch, that you’re trying to upload over Blynk.air needs to have a higher firmware version number than the original sketch.
Simply edit that line of code, re-compile and try again.
