Decent Espresso

What's new in Decent Scale v1.2

New scale features

  1. The top of the scale is now a scratch resistant, frosted, matte plastic.
  2. The displayed scale weight is not changed when you touch buttons.
    • Your finger is detected currently approaching or touching a button, and the weight display on the scale keeps the current weight until your finger moves away.
  3. A new kind of touch sensor chip is now being used, which should resolve the button press problems that previous models occasionally had.
  4. Decent Scale v1.2 is limited to a maximum of 1000g of weight on the scale platform when powering up.
    • After powering up, v1.2 can handle up to 2000g of weight on the scale.
    • If more then 1000g is on the scale when powering up, the scale will not measure any additional weight.


New BLE features

  1. Turn the scale off with a BLE command: 030B030000000B
  2. Firmware v1.2 and newer includes a millisecond accurate timestamp with each weight measurement.
    1. This is (1) to help you calculate flow rate, (2) to know if you lost a weight measurement or (3) have received an out of order weight message.
    2. Firmware v1.2 and newer sends weight with a timestamp, as a 10 byte message.
      • Firmware v1.0 and v1.1 sends weight as a 7 byte message.
BLE bug fixes
  1. When BLE connected, the O button no longer auto-tares, and is instead correctly controlled entirely by the app.
  2. The weight change feature has been discontinued as of firmware v1.2.

What's new in Decent Scale v1.1

    New scale features
    1. High availability mode.
      1. The scale will turn on by itself when USB power is turned on. It will never turn off, unless told to via BLE.
      2. BLE pairing never times out, so your app can always connect
      3. Combining these two features, your app can enjoy very high reliability, always knowing the scale is on and available to your app.
      4. Your app can automatically and easily recover from power loss.
    2. Power on with the square [] button to turn the scale on with no bluetooth (and thus, no blinking blue light)
    3. Auto power-off during idle now extended to 10 minutes (previously was 2 minutes) Only applies when using batteries.
    4. Purple LED always means "finger detected touching a button"
    New BLE features
    1. Command to set grams vs ounces (not required to do this manually)
    2. Command to see if running on USB power vs batteries
    3. Command to find out scale's firmware version number
    BLE bug fixes
    1. The O button should be under software control via bluetooth, and should not cause taring automatically
    2. Sometimes a command sent to the scale is lost, and has to be sent twice (currently worked around invisibly by the app)
    3. Cannot determine current battery power via bluetooth
    4. Long press on O and [] buttons not differentiated from a short press.
