CR3XX-CELL2XX now supports the CELLULAR RADIO UPDATE and CELLULAR RADIO UPDATE FILE terminal commands.

The CR300-series data logger, when it is a DHCP server, no longer activates the watchdog reset when receiving DHCP packets larger than 500. This change improves communication reliability over the RNDIS port and the integrated WIFI option when configured to create a network.

An internal Wi-Fi update is available. After updating the CR300 to CR3XX.Std.09.00.obj, or later, the internal WIFI can be updated by sending CR300_WIFI_1.7.5.obj. This updates the WIFI module to properly receive broadcast packets from the Access Point it is joined to. Prior to this update the CR300 would not respond to the Device Configuration Utility IP search feature.

After updating to CR3XX.Std.09.00.obj, or later, the Device Configuration Utility “Send OS” tab will work as expected. Prior to this fix several attempts to send the OS may have been required.

The terminal command SHOW CELL INFO for the CR3XX-CELL2xx series no longer causes a reboot.

Memory for TLS now is allocated correctly when TLS connections are used in Slow Sequence scans.

TriggerSequence() no longer prevents the CR300 from dropping into low power mode.

Fixed an invalid memory read error when using SerialOut() when used with the TCP/IP socket handle. The memory read error would cause the datalogger to watchdog.

Fixed and issue with PreserveVariables() that would cause memory corruption when restoring variables. This would cause the CR3X0 datalogger to become unresponsive and watchdog right after reboot.

Added a watchdog to monitor a failed OS send attempt. If an unexpected error occurs causing the OS upload to be terminated mid process, the datalogger will watchdog in 40 minutes. When the datalogger watchdogs, the program set to “run on power up” by the run options, will compile and restart.

A datalogger OS may be sent remotely using the "Logger Control" tab in Device Configuration Utility if the running program has been stopped. When the program is stopped, the SW12 port and communication ports will remain in the same state. Prior to this change, sending an operating system remotely via the "Logger Control" tab would cause the datalogger to reboot before accepting the OS. The reboot was problematic over cellular communications because of the latency in the renegotiation process. Device Configuration Utility will time out aborting the OS send before communications are reestablished leaving the datalogger in an idle/no program state. Note the best practice for sending an OS remotely is through File Control in either Device Configuration Utility or the LoggerNet Connect screen. Sending an OS with this method does not require you to stop the running program first. The OS has not changed the behavior to File Control.

The Internal cell modem firmware in the CR3x0-CELL2xx series can now be updated over the air. See app note 3T-M for directions.

Fixed an issue with the internal cellular modem that occurred when trying to re-connect to the network after a "PPP" error with detail "9" was logged in the cellular log.

Updated radio diagnostics to include radio firmware version.

PWM() now allows floats in the Period parameter.

GPS() now accepts values prefaced with + or -.

Duplicate measurement instructions are now allowed in stacked scans. An example of a program that uses stacked scans is a program that may contain a pre-scan with a set number of scan counts. Once the pre-scan count is reached the program will move to the main scan and run.

The reset parameter in MaxRun() and MinRun() now behaves like AvgRun().

You can now use pointers in the ArrayLenVar parameter of ArrayLength().

You can now use pointers in TypeVar parameter of TypeOf().

(URGENT) An issue was found in CR3XX operating systems with a revision number less than 06.00 that could cause the datalogger to become unresponsive in some systems after 50 days. CR3XX operating system version 06.00 and greater resolve this issue. It is highly recommended that all CR300s and CR310s be upgraded to an operating system with a revision number that is 06.00 or greater.

(WARNING) Upgrading the Operating System could reset all CR300 settings back to factory defaults when updating from an operating system prior to version 05. Sending this Operating System remotely can be done but is not recommended. To restore settings after the update, it is recommended that a backup be made of the current datalogger settings or take programmatic measures to ensure your settings can be restored. This can be done using Device Configuration Utility’s (DevConfig) backup utility or the CRBasic instruction SetSetting(). Watch the Video Tutorial: Sending an OS to a Local Datalogger.

(NOTE) This operating system release is a bug fix release. There are no new enhancements or features added except for the items listed below.

Updated the watchdog to verify that the run program tasks are always in a task queue. If the run program task fails to be in the task queue, the datalogger will now watchdog and increment the watchdog counter in the status table. This was done to ensure the datalogger run program task is always working correctly.

Updated the datalogger operating system USB driver to detect transmission timeout errors.

Modified the DHCP server startup when using RNDIS to check for a USB connection before starting. This prevents the DHCP server from incorrectly responding to DHCP requests on all Ethernet, Wi-Fi, and RNDIS interfaces at start up.

Updated the AM25T() instruction to turn excitation off before starting AM25T measurements. Prior to this change excitation was left on. This would cause certain measurements that did not need excitation to be read incorrectly.

Fixed an issue that caused the Ethernet connection to reset when the DHCP was not in a bound state.

Updated the text for the default network so it is consistent with the text displayed by other Campbell Scientific dataloggers.

Modified the operating system to disable all sleep modes when USB is connected.

Fixed an issue when using SerialOpen() and SerialIn() with Format 0. If a PakBus sync byte was found, SerialIn() could drop into a PakBus mode sending all received data to the PakBus task, which caused SerialIn() to fail.

Fixed an issue when using SerialOpen() on COM1 that could keep the logger awake for an extra 15 seconds after a SerialClose() was called.

Changed the default username and password used by the datalogger FTP server. The new username and password are now both NULL. This change will require the user to set their own username and password (both required) in order to use the datalogger FTP server. Neither the username or the password can be blank. This was done to better secure the datalogger FTP server against malicious attacks. This change does not affect the FTPClient() instruction.

Fixed an issue that caused the DHCP server to respond when Wi-Fi was configured to "Join a Network".

Updated WebSockets to support the logon command that is used by the internal web pages.

Fixed an issue when transmitting from RS232 that could cause delays between bytes and slow the task down.

Fixed Files Manager when using option 3209. Note: Capture will alternate between writing to two files "_0" and "_1" to allow for wear leveling of the flash memory.

Updated Files Manager to delete the file if open fails.

Fixed a signature issue that prevented PreserveVariables() from working.

Updated PreserveVariables() to store values before an operating system restart.

Added Settings.PPPInfo and Status.PPPInfo.

Updated Status.MemoryFree to reflect memory used for communication buffers.

Updated table creation to always store a timestamp when using TrigVar parameter.

Fixed a table timestamp issue that occurred when using tables that did not contain the DataInterval() instruction and the datalogger was waking up from a sleep state.

Updated time of maximum and time of minimum to not inherit units in tables.

Fixed an issue with table allocation when the table interval could not be determined which caused the requested number of records to be overwritten.

(URGENT) An issue was found in the previous operating systems that could cause the datalogger to become unresponsive in some systems after 50 days. This operating system resolves that issue. It is highly recommended that all CR300s and CR310s be upgraded to this operating system.

(WARNING) Upgrading the Operating System could reset all CR300 settings back to factory defaults. Sending this Operating System remotely can be done but is not recommended. To restore settings after the update, it is recommended that a backup be made of the current datalogger settings or take programmatic measures to ensure your settings can be restored. This can be done using Device Configuration Utility’s (DevConfig) backup utility or the CRBasic instruction SetSetting(). Watch the Video Tutorial: Sending an OS to a Local Datalogger.
