EL-Client sync failed! #330

Hi

I am using ESP-01 and Arduino Pro Mini 8Mhz and keep getting "EL-Client sync failed!". I have searched through the forum and reduced the Pro Mini baud rate to 19200.

I have tried both the stable version and the alpha version and still getting the same error. Any ideas what else should I try?

I have found the problem. The power source of the setup was powered with a FTDI converter and its was plugged my pc. For some reason, the serial port and UART between ESP and Pro mini is conflicted and the Sync failed. When I connect it to a battery pack, everything is fine.

Thanks for the wonderful work.
