The COBRA firing systems ecosystem consists of many devices including the 18R2, 18M, 36M, 72M, 6M, and Audio Box. Firmware is the embedded software in our hardware that gives life to the device. COBRA is continually striving to improve products, and as we add feature enhancements to each device, COBRA releases new firmware versions to support the newly added functionality. While some new features may not always be available for older hardware, all COBRA systems support the latest firmware versions within our universal system design where all systems work happily together as a single family of products.
In addition to performing firmware updates to hardware firmware, COBRA also performs software upgrades to the COBRA Control Panel Android app available online from Google Play.
To determine compatible firmware versions across the COBRA Firing Systems equipment portfolio please see Firmware Figured Out.
To perform a firmware upgrade or downgrade please download the COBRA reprogramming software.
Below is a list of the current beta and stable firmware releases for your COBRA system. To learn more about our firmware release process, see What is our firmware release process?
Additional support is always available via email at help@cobrafiringsystems.com.

| December 6th, 2021 |
18R2 - Fixed an issue where two cues on the same channel and firing at the same time could cause the module to not display in the arm count and fire. - Added scripting error code 57 to prevent the use of STEP events when using SMPTE Timecode. - Fixed a rare issue where 18R2s would not allow syncing new modules. - Fixed an issue that caused DMX STEP scripts to not show correctly on the Control Panel. - Fixed a display bug that showed the incorrect channel/cue on the 18R2 as being the last to fire. 36-72M - DMX Events can now be disabled when using the Disable Firing feature on the 18R2. - Fixed bug that prevented the 36/72M from showing on the Control Panel if you force refresh the module count while armed. |
|
| June 2021 | 6.0.5 is a patch release to 6.0.4 to address a few issues in 6.0.4. 18R2 - Fixes partial lock-up issues that could occur when changing the channels while a script is actively firing or paused. -Fixed issue with alternate events causing ER33 on certain 18R2 hardware versions. - Fixed issue with alternate events firing channel zero instead of correctly assigned channel. - Scripts are now saved correctly on the 18R2 when power-cycling the remote after changing the script attributes from the Control Panel. 36-72M - The modules will now send DMX zero values when in TEST or ARM if a DMX universe is set on the module. Previously the zero values were only sent while a script was running. - Fixed minor display issues that caused text overlapped on the LCD while in program/sync mode. |
