Driver Config

Hello,

I recently acquired this Convoy S2+ triple ( Another Convoy S2+ Triple for sale -Sold-)

I think it’s a Bistro UI but not sure.

I clicked 15+ times and went thru all 8 config. I cannot find the mode I wanted. Can you guys help me?

I wanted low med high with memory.

I am able to get to low med high, but cannot get the memory mode or always start on low. It just to the next mode when I turned it back on after 5 seconds.

Just can’t get the memory mode to work…

when I clicked more than 15+ times, the following occurs

1 blink followed by very fast strobe
2 blinks followed by very fast strobe
3 blinks followed by very fast strobe
4 blinks followed by very fast strobe
5 blinks followed by very fast strobe
6 blinks followed by very fast strobe
7 blinks followed by very fast strobe
8 blinks followed by very fast strobe

You get the “buzz” after the 15 clicks?

2 is mem/nomem.

5 then 3 is 3-mode (presuming l→h order).

"Bistro" firmware
=================

This is designed for an ATTiny25V-based driver with off-time capacitor 
and FET+7135 power channel configuration.

The interface is as follows:
  (see bistro-ui.png for a quick start)

  While off:

    - Fully click and release to turn the light on.  It will go to the 
      first mode or the last-used mode, depending on whether you enabled 
      mode memory.

  While on:

    - Short tap: Do a short (less than 0.5s) half-press to go forward to 
      the next mode.

    - Med tap: Do a medium (0.5s to 1.5s) half-press to go backward to 
      the previous mode, if medium-press is enabled.

    - Long tap: Do a long (longer than 1.5s) half-press to reset to the 
      first mode (if mode memory is turned off).

    - Or fully click and release to turn the light off.

    - Short tap a bunch of times (15+ taps, or until the light stops 
      turning on) to enter config mode.

  Hidden modes:

    - Go backward from moon to access the hidden modes.  They are, in 
      order:

      - Turbo (just like the regular turbo)

      - Tactical / police strobe (7 Hz / 14 Hz alternating)

      - Battery check / beacon mode
        It should blink out the voltage in whole numbers then a '.' then 
        tenths.  So, for 3.6V it would blink out "--- . ------".  
        Voltage range is from about 2.5V to 4.4V

      - Biking flasher (2-level stutter beacon, 1 Hz)

  Configuration options:

    The config mode has several options.  It will blink out a number to 
    show which option is active, then "buzz" or "stutter" for a bit.  
    Click during the "buzz" to select that option.  Some options may 
    enter a secondary config mode after the light turns back on.

    Options include:

      1. Muggle mode / simple mode.  Good while lending the light to 
         others.  It overrides other config settings temporarily:
         - low/med/high, in that order, with high at about half power.
         - no moon, no memory, no medium-presses, no hidden modes
         - the only config option is the option to exit muggle mode

      2. Mode memory.  Off or on.

      3. Moon.  Select to turn moon mode on or off.  This is in addition 
         to the other regular modes, so you get 2 to 9 levels when moon 
         is enabled.

      4. Mode order.  Low to high, or high to low.

      5. Mode group.  Choice of 1 to 6 regular modes from low to turbo, 
         or one of 3 special groups.  After clicking, the light should 
         come on in a special group-select mode.  In this mode, it 
         slowly blinks 9 times, pauses, then repeats.  Turn the light 
         off after N blinks to select mode group N.
         The mode groups are: (output is approximate)

         1. 1300 lm only
         2. 8, 1300 lm
         3. 8, 235, 1300
         4. 8, 104, 506, 1300
         5. 8, 75, 254, 642, 1300
         6. 8, 50, 167, 366, 757, 1300
         7. 140, 1300, strobe
            (police modes)
         8. bike flasher, battcheck, 8, 140, 1300
            (biking modes)
         9. 4, 36, 140, 500, 1300
            (like group 5 but lower)

         Example: To select group 3 (low-med-high), let it blink three 
         times then click the button.

         Note: 140 lm means 100% on the 7135 channel, while 1300 means 
         100% on the FET channel.  Both are no-PWM modes.

      6. Medium-press.  Off or on.  If on, a medium-press will allow 
         going backward through the mode sequence, and hidden blinky 
         modes will be accessible.

      7. Thermal calibration.  Set the temperature at which the light 
         will begin stepping down to cool itself off.  After clicking to 
         select this, the light should turn on in a special thermal 
         calibration mode.  It will start at a medium-low brightness, 
         wait a second or two, then step up to turbo.

         - To turn off thermal regulation, click within the first second 
           (while the output is relatively low).

         - To set a new maximum temperature, leave the light on until 
           you think it is too hot, then turn it off.  From this point 
           on, the light will use that new temperature as its maximum 
           allowed heat.

           Note that there may be a delay between when you feel the heat 
           and when the MCU feels the heat, so the value saved may be a 
           little bit lower than expected.

      8. Factory reset.  Change all settings back to default.

i did not hear any buzzing.

I tried 5 but it has moon, low and high. I turn it off and turn it back on, goes into the special mode (strobe/blinkies).

This is one funky driver.

okay,

I was able to go into the 5 but when tried disable or enable the memory, it doesn’t work. I will go to the next mode when I turned it back on.

How long does I have to leave the light on for the memory to kick in? 3 sec?

damnit, it keeps turning on to the next mode… GRRRrRrr

Do you have a standard convoy s2+ tailcap? I’ve noticed in the past that sometimes the draw through lighted tailcap will affect the mode selection and can change how you get into the menu. Try with a standard cap or just using something metal to connect battery ground to flashlight body to act as a switch.

No, got it like that. No standard s2+ tailcap.

I think ‘buzz’ means a fast flicker, not an audible sound

I used a metal and did what tru3s1lv3r suggested, seems to activate memory function. But I don’t have a regular s2+ tailcap. Can’t find a black tailcap on eBay. :cry:

Make sure you don’t have the Muggle mode ON( because it overrides other config settings)

I configured it to group 5 so it shouldn’t be in muggle mode.

Also when using a paperclip, it has memory. So it’s should be the tailcap.

Anyone have one to sell?

I contacted Richard from mountain electronic, haven’t got a reply. His out of stock for the black s2+

tru3s1lv3r, you built this light, did the memory mode work for you when u had it?

Anyone know where I can get the tailcap for s2+?

Simon at the Convoy store on AliExpress. You may have to pm him on AE but he usually will sell whatever parts are needed even if they are not listed on his AE site.

Gotta love those configurable drivers…
