Changelog

Develop

  • Change license year to 2022
  • MQTT: Improve module implementation
  • MQTT: Add optional SSL connection type
  • MQTT: Add cayenne async demo, publish-mode only through ring buffer
  • MQTT CAYENNE: Completely reworked with asynchronous MQTT instead. Improves performance to transmit more data in one shot
  • MQTT client: Add poll periodic event for event callback
  • Port: Improve ThreadX port
  • CONN: Enable manual TCP receive by default, to improve system stability
  • Timeout: module returns ERRMEM if no memory to allocate block
  • Add esp_at_binaries from Espressif, used for library verification (official AT firmware)
  • Add optional AT+CMD? command at reset/restore process, for debug purpose for the moment, only
  • Add function to get ESP device used for AT command communication
  • Fix lwesp_get_min_at_fw_version to return min AT version for detected ESP device
  • SNTP: Improve module comments, change timezone variable to int16_t
  • SNTP: Implement global callback when command is to obtain current time
  • SNTP: Add synchronization interval config, available with ESP AT 2.3.0 or later (ESP32-C3 only for the moment)
  • SNTP: Add option for readin current SNTP configuration
  • SNTP: Add option to automatically read SNTP data on +TIME_UPDATED event (requires ESP-AT v3.x or newer)
  • ERR: Add option to get response to ERR CODE: message if command doesn't exist and put it to result of command execution
  • Fix min at version for ESP32 to 2.2.0
  • Add LWESP prefix for debug messages
  • Update code style with astyle
  • Add .clang-format draft - remove astyle support
  • SSL: Added experimental support
  • FS: Added support for erase and write operation
  • Code improvement: Change multiple local variables to single structure
  • Date&Time lwesp_datetime_t and use generic struct tm instead
  • CONN: Add validation counter to ensure netconn object matches connection object and that there was no connection close/re-open in between
  • Minimum supported AT version is now v3.2.0 (ESP32, ESP32-C3) to support new MFG write operations
  • Added support for ESP32-C2 and ESP32-C6 AT commands
  • SYSFLASH: Split System flash and Manufacturing data to separate commands, following new breaking changes for ESP-AT firmware
  • WPS: Break API compatibility to configure the feature, by adding minimum security level parameter in the lwesp_wps_set_config function

1.1.2-dev

  • Add POSIX-compliant low-level driver (thanks to community to implement it)
  • Prohibit transmission of too long UDP packets (default), can be disabled with configuration option
  • Split CMakeLists.txt files between library and executable
  • Move esp_set_server function to separate file lwesp_server.c
  • Use AT+GMR command just after reset/restore to determine ESP device being connected on AT port
  • Minimum required AT binaries are now 2.3.0 for ESP32/ESP32C3 and 2.2.1 for ESP8266
  • Connection status is acquired with AT+CIPSTATE or AT+CIPSTATUS, depends on Espressif connected device
  • Add optional full fields for access point scan with LWESP_CFG_ACCESS_POINT_STRUCT_FULL_FIELDS config option
  • Add optional keep-alive periodic timeout to system event callback functions. Can be used to act as generic timeout event
  • Improve station manager snippet with asynchronous mode
