Requirements

Note

Before OTA make sure to go through the list below.

• Make sure you have physical access to the device before starting the update process.
• Do not power off the device during the firmware update.
• If Site has Enapter Gateway it needs to be updated to version 1.8.9 or higher.
• Remove the Dryer Control Network (DCN) before updating the firmware (no need since 3.3.0).
• Electrolysers connected to DCN/IDCN should be version 1.10.0 or higher, otherwise monitoring and control from Electrolyser Web GUI or Modbus TCP interface won't work.

Change Log

New Features

• Add support for new HW.

Bug Fixes

• Stabilize provisioning process.
• Improve NTP synchronization process.
• Improve DCN performance.
• Make hostname unique for WiFi interface. (Previously all Enapter modules have espressif as a hostname, now it will be ENP_<YOUR_DEVICE_ID>).

Compatibility Matrix

Please carefully check the compatibility matrix for the 3.7.0 firmware version with the previous version.

Legend:

• C - fully compatible;
• NC - not compatible;
• PC - party compatible, check additional notes.

	3.6.0
OTA Upgradable	C
Rollback	C

Functional Depreciation Statements

Modbus Compatibility

• Begin with firmware version 3.6.0 Dryer input registers are deprecated, holding registers should be used instead.

Known Bugs List

The list below contains the most important problems in the firmware and their solutions.

• DCN may assign an IP address to devices (computers, mobiles) connected to Wi-Fi AP associated with DCN enabled Enapter devices.

  Solution:

  • Delete the DCN from the Enapter Mobile App and create it one more time.
  • If it is possible try to separate the DCN from your main network environment by connecting the DCN to another WiFi AP, no need to separate one DCN from another.
