Instead of leaving the old code in comments, it would be better to simply drop it.

@atanisoft Fixed. Please kindly check it. Thank you.

it looks like your PR is introducing a mix of TAB and SPACE characters resulting in a jumbled mess of formatting. Can you please reformat your additional code to match the existing formatting?

instead of a for loop using fixed sizes for chunks, please consider a loop similar to below (note this is not tested):

while(sent_bytes < size) {
  size_t sent = _client->write(&payload[sent_bytes], std::min(size - sent_bytes, _chunkSize));
  if (sent < 0) {
    log_e("Failed to send chunk!");
    break;
  }
  sent_bytes += sent;
}

Note that there is ZERO guarantee that the write call will send the full block size you request it to send thus you must check that it actually sent data and only then move the data starting point. The check for negative sent byte count is to check for sending errors.
