How to append all log NOT only the last line of recived messages

[aluis-rcastro]

It's a long time since I did this program, however if I'm not missing something, at a glance seems like you are likely not doing things the correct way. Opperations like "read" and "write" (to file) cannot be performed inline as such since are not done by callback functions. You should catch file events as "read done/write done" to trigger the corresponding read and write process.

Refer to the file "GotText" component, placed at the 2min57s on the folowing video:

How to Read File in MIT App Inventor 2 [ File Component ]

Note that you start reading with the "readFrom" method, but file content acquisition is effectively made upon "GotText" event. This happens because java processing time occurs much faster thatn peripherals timings, so a synchronization feature as such is needed.
