* add opportunity for more than one retry to _uploadReadByte * an alternative timeout-based method to making _uploadReadByte more resilient * move timing variables in the correct scope * implement and use client.getTimeout instead of hard-coded timeout in _uploadReadByte * add missing return * some refactoring to address respecting the timeout in a potentially deadlocked connection * fix spelling in comment * address review comments; move impl to cpp file for getTimeout, and remove local variable for currentMillis * remove redundant cast * need to check for timeout outside the inner while as well * update WebUpdate example to print something in unexpected callback condition * update log_e messages per review comments
