v02.00.00

Important Topics

  • Express mode functionality is now supported. This feature enables the operating script to be executed by bypassing the network connection and NEQTO Console authentication otherwise required for NEQTO device startup.

  • Power-saving functions are now supported as the Sleep object.
  • The LTE modem firmware version (RK_02_01_02_10_108_54) of the Spresense LTE extension board was applied. The LTE modem firmware version can be upgraded by using the local update tool or by executing FOTA. Using the local update tool may take at least 20 minutes, and FOTA may take at least 30 minutes. It is recommended to update using the local update tool. (LTE-M version only)

New Features

Improvements

  • Fixed a bug that could cause the device to reset when executing [throw '#nqEXIT'].
  • Fixed the nqMQTT object to raise an exception instead of resetting the device when internal resources are exhausted.
  • Fixed a bug which could have caused the connection error code “Connection failed” to become “Other error” in the MQTT and nqMQTT objects.
  • Fixed the event message type to be notified as "User" instead of "Engine" when using the eventNotify method of the nqService object in the Machine Driver script (fup.js).
  • Fixed a bug where the binRead method of the nqFOTA object would return an ArrayBuffer of 0 bytes instead of returning null when there was no data to be read.
  • Fixed a bug where transmission may have failed if a 1-byte character was specified in the eventNotify method of the nqService object.
  • Fixed a bug where unexpected data may have been written when only numerical characters were specified as the write data in the write method of the Storage object.
  • Fixed a bug that caused the device to reset when the number of retries were exhausted if a finite number of automatic reconnection retries was specified in the connect method options of the MQTT object.
  • Fixed a bug that caused the system LED to blink differently from the specification when reloading scripts from Safe Mode.
  • Fixed a bug that delayed alarm callback time with setAlarm of the rtc object by 1 second.

Changes

  • Changed the transmission complete conditions related to the checkSendComp method of the UART object from only "send buff empty" to both "send buffer empty" and "hardware send complete".
  • Changed the received signal strength indicator value obtained in the return value of the getSignalQuality method of the nqWiFi object to -255 when not connected.
