Then there is an expert info in Wireshark which says "No encryption key set - can't decrypt". If a connection is lost, the binding will wait this time before it tries to reconnect. Introduction - ESP32 has two I2S peripherals. A next date for one has not yet been set; to keep up to date send mail to the Any application which uses COSE for security services first needs to determine what security services are required and then select the appropriate COSE structures and cryptographic algorithms based on those needs. and read more details at: ETSI is also periodically running interoperability testing events (“plugtests”). In addition, base64 encode/decode binary data. CoAP has been an approved standard since 2013-07-11 (draft-ietf-core-coap-18), and there is little point in keeping support for pre-13 versions of the protocol around. 3.2.5 to 3.4.3: coap.version: Version: Unsigned integer, 1 byte: 1.6.0 to 3.4.3: Go Beyond with Riverbed Technology.
