TR75A / Versions 1.04 or lower

Update Details

• Some operations of the battery level warning have been revised.
  - Revised battery warning recovery criteria to avoid sending low battery warnings repeatedly.
  - Changed the state of battery warning sent when a low battery recovery has occurred from 1 (normal) to 81 (recovery to normal).
  - Changed the specifications for sending any untransmitted battery warnings when low battery recovery has occurred.
• Added functionality to send the state of Warning Lifted (state:82) when the warning settings have been changed, the recording has been started, or the device has been reset while in a warning state.
• Functionality was added whereby if upon recovery from a sensor error, an upper/lower limit warning is still active, the status (state:83) will be sent.
• When sending data via a proxy server, the connection is now made using a host name instead of an IP address. (White list compatible)
• Previously command processing was aborted when the response from an HTTP server was R=0 (command rejected). Processing has now been modified so that a request is issued for the command specified by the flag contained in the response.
• Fixed a problem that occurred when the auto-upload interval was set to 24 hours, where recorded data was being sent every 5 hours and 50 minutes.
• The measured values displayed in warning e-mails have been changed from the “instantaneous values” at the time of warning judgment to the “max/min values” during the specified judgment time.
• Sensor error information was added to Bluetooth advertisement packets.
• Fixed an issue that occurred when resending multiple warning data after transmission failures (due to low battery, etc.), where the battery status at the time of successful transmission was reported instead of the battery status at the time of the warning.

Important Notes for Using TR75A with T&D Data Server

Please make sure to also update the T&D Data Server to the latest version (2.35 or later, available from here).
If you use the TR75A firmware Ver.1.05 with T&D Data Server Ver. 2.30 - 2.34, and a warning has occurred, an error will appear in the T&D Data Server log monitor due to TR75A specification changes.
