SD card reader with publish

Dear all,

I’would like to publish on the cloud a basic text file (10 lines) who is stored inside a SD card (in .txt format) on the cloud using an Electron. I’m using the SdFat library.

Basically, I would like to change the Serial by Particle.publish() on the code just bellow:

myFile =“test.txt”);
if (myFile) {
while (myFile.available()) {

Thank you in advance for your help.

Particle.publish() has its limitations.
You can only publish at an average rate of 1 event per second and the payload for each publish is limited to 255 characters.
If that is OK for you, you should collect your single bytes you get with into a char[] buffer and then publish the content of that buffer in one go.
