Otherwise please let me know. \r\nWe need to send a huge block of data (several kbytes) to our devices over coap/lwm2m. \r\nWe will split this huge block of data into smaller packets on application layer (lw2m2).\r\nBut we would to avoid to have to split this data into a endless number of packets with just a few bytes size.\r\nSo here my questions: \r\n- Is the coap layer in mbed supporting block transfers & segmentation?\r\n- Whats the maximum payload size for coap packets  the mbed stack can deal with?\r\n- May it be possible to influence this value by redefining buffer sizes, defines etc?\r\n- If yes, where?\r\n\r\nThanks in advance for your help.\r\n\r\nKind Regards\r\n\r\nMartin Tomasini\r\n  \r\n"}}
