Handheld Scientific, Inc.Page 11 of 254. Command Mode and List of commands4.1 Entering and Exiting Command ModeCommand mode is used to configure adapter features. In this mode, the keystrokes from thekeyboard are intercepted and interpreted by the Adapter as command. The responses to thecommands are sent to the host, via any enabled and active interfaces (Bluetooth and/or USB).This is the biggest innovation in this product. With other products, such as those programmablekeyboards, a user needs to either rebuild the firmware, or install some kind of configurationsoftware. Either way it is very involved. Setting up the build environment requires a lot of workand expertise. Maintaining a configuration software isn’t easy, given the number of operatingsystems and evolving environment. Our approach is truly platform independent. It works withany operating system, without installing additional software. Moreover, the feature is in theAdapter itself. As long as you have the Adapter, you can use the feature, independent ofanything else.To enter command mode, plug the adapter in a host or pair the it with a host. Open a text app(i.e., Notes, Notepad, Word, or anything that can display text). Make sure when you type on thekeyboard connected to the adapter, the keystrokes appear on the app. Press and hold the modebutton until the following text is emitted (which will happen in 2 seconds):Bluetooth Adapter Firmware v5.2.0Copyright (C) 2019 Handheld Scientific, Inc.Type help or ?L1>Alternatively, you can use the shortcut to enter command mode, so you don’t need to reach tothe adapter for pressing the button. The default shortcut is ctrl+alt+ins. That 3-key combinationis pretty much like the well-known ctrl-alt-del 3-finger solute in Windows. But instead of theDelete key, the Insert (ins) key is used. In the unlikely event that this 3-key combination is usedby some other application, you can change to use another key combination, or even disabledthe shortcut. See “set com_mode_shortcut“ in the command list.If you see other non-English characters instead of the above text, make sure the languagesetting of the operating system is English. You may also need to change the keyboard layout toEnglish since the commands are in English. Once in command mode, features such as timersand key mappings are disabled. In other words, you need to exit command mode to see themworking.To exit command mode, press the mode button again or type the “exit” command.The command prompt, “L1>”, indicates which layer it is currently on. Please see “layer” in theAdvanced Features section. The firmware version in the above text may be different since wecontinue making improvements and releasing new firmware.4.2 List of CommandsCommands are very similar to those in Unix Shell where tokens are separated by space andterminated by <Return> or <Enter>. All commands are in lower case. In the following commandlist, curly brackets {} signifies a name that needs to be substituted by the actual value. For |
