If you get a _BUSY return code, it does not always require the application to do a soft-reset. Same applies for other scenarios where the buffer is full. Retrying (with a timeout) can be a better way of handling such return codes.</p> <p></p> <p>Cheers,</p> <p>Håkon</p><div style="clear:both;"></div>
