Hi, i have the tags:
And i need change the number writed on Tags, because some numbers is 0 or F ASCII, i need generate a number sequence on free space, this number can be Read with the module:
With SoftwareSerial library and the read() function, is possible change the writed numbers?
The AliExpress offer doesn't provide any information that the ear tag is writable. Why do you think you can write to it?
And i need change the number writed on Tags, because some numbers is 0 or F ASCII,
What the problem with some digits being '0' or 'F'?
With SoftwareSerial library and the read() function, is possible change the writed numbers?
No, definitely not, just because the read() function reads from the module and does not write to it.
The offer only advertises a "read" module, no hint that it may write, so I wouldn't expect it to be able to write. Buying such stuff on AliExpress isn't a good idea if you don't know exactly what you're buying, because without some minimal documentation it's almost worthless.
