Revision History

  • 4.0.3

    • Always show BLE error info
    • Update dependencies

  • 4.0.2

    • Fix Module Loading Error on macOS

  • 4.0.1

    • Fix Module Loading Error

  • 4.0.0

    • The node category is now Network rather than Input and Output.
    • Improve stability on Linux by introducing BlueZ 5 D-Bus API
      • On Linux, this node is no longer dependent on the HCI socket library, which has lots of problematic issues that caused inconsistent results with old BlueZ CLI tools.
      • Note that when Node-RED process is run by non-root user, add the user to bluetooth group so to access BlueZ D-Bus API. For example, run sudo usermod -G bluetooth -a pi prior to starting the process if it's run by pi user.
      • BlueZ's BLE scanning seems to detect devices having random address type. But not sure if such devices work with this node properly.
      • Tested on Raspbian (4.19.97-v7l+) and Raspberry Pi 3/4.
        • With the following packages
          • bluez 5.50-1.2~deb10u1
          • bluez-firmware 1.2-4+rpt2
    • Improve BLE Device Scanning UI/UX
      • Check BLE Scanning in order to start scanning, and Scan Result select box will be fullfilled automatically whenever devices are found. The update will be performed every 10 seconds. The first scan result will appear after 5 seconds since the scanning starts. See the updated README document for detail.
    • GENERIC_BLE_TRACE environment variable is no longer working. Use DEBUG environment variable instead.
      • DEBUG=node-red-contrib-generic-ble:index is compatible with GENERIC_BLE_TRACE=true.
      • DEBUG=node-red-contrib-generic-ble:* will output all trace logs within the project.
      • DEBUG=node-red-contrib-generic-ble:index:api will output all API endpoint access logs.
      • DEBUG=node-red-contrib-generic-ble:noble:* will output all trace logs under src/noble modules.

  • 3.1.0

    • Support Node.js v10.x LTS (Fix #14 and #17)

  • 3.0.0

    • Refactor entire architecture
    • Peripheral connections are retained until it disconnects
    • Characteristic subscriptions are retained while the ongoing flows are running (will be unsubscribed on stopping them though)
    • The max number of concurrent BLE connections is 5 or 6 according to this document

  • 2.0.4

  • 2.0.3

    • Fix an issue where noble looses a reference to a peripheral after it is disconnected

  • 2.0.2

    • Fix an issue where Write operation cannot be performed properly (#4)

  • 2.0.1

    • Fix an issue where Select from scan result failed to list characteristics

  • 2.0.0

    • Add Poll Notify Events message support so that Generic BLE out node can start to subscribe the given characteristic events
    • Support characteristic query by one or more uuids
    • Add Mute Notify Events to Generic BLE config node for this node to avoid unnecessary device connection for event subscription
    • Replace RED.log functions with node logging functions as possible to offer precise logging control via UI
    • Add Operation Timeout to Generic BLE config node to set the waiting time for Read/Write/Notify response per characteristic rather than per device
    • GENERIC_BLE_OPERATION_WAIT_MS is introduced for default Operation Timeout value
    • Remove Listening Period from Generic BLE config node
    • GENERIC_BLE_NOTIFY_WAIT_MS is removed

  • 1.0.2

    • Improve README
    • Add an example flow file available from the editor UI

  • 1.0.1

    • Fix an issue where custom characteristics cannot be listed on the Generic BLE config node dialog

  • 1.0.0

    • Fix an issue where some devices cannot be discovered within a specific time window even after they can be connected
    • Fix an issue where the Scan Result select widget didn't show the same item as the stored device info
    • Update Scan Result option list whenever Local Name is resolved
    • Improve stability by fixing minor bugs

  • 0.1.0

    • Initial Release (alpha)
    • node-red keyword is not yet added
