writeBuffer not writing all bytes

[ricomercader]

Hello,
I am having an issue when writing bytes with a certain device. I can read/write several messages. The read messages can be of 100+ bytes. However, when writing, I am having success with short messages (up to 12 bytes), but then, trying to write 32 bytes, only 24 of them get written. I am able to obtain the amount of written bytes through the output of writeBytes function, but what should I do next? Should I rewrite with an offset? Has something like this happened before?
Thanks

Here is some detail on the bytes I sent. If 24 bytes were sent, that stopped right before a sequence of four zeroes. There is a zero in the second byte, so it doesn't look as if it was the delimiter, but it is possible that having some many zeroes could be interpreted as end of sequence. Let me know if I can provide any other data.

Sometimes the OS only let's you write a certain amount of data to the serial device. You need to offset the data you want to write and need to write the rest of the data with a second call.

Hi there, just wanted to say that it worked!
As a suggestion, I would recommend mentioning this approach in the examples and in the detailed documentation of writeBytes function.
