Module can use USB to TTL in the normal operation of the problem is to put the program downloaded to the MCU to electricity after sending I define command has also been some puzzling data sent ten seconds and then stopped again a few seconds to what's the problem with repeated bosses to help have a look at the program

Are you someone who help

CodePudding user response:

If need to feed the dog! Delay is too long!

CodePudding user response:

Capital, capital, capital b

CodePudding user response:

You this serial assistant can also check MCU send data and data from 8266 to send?
