OK, you don't use the latest version of the java configurator from github?!

No. But now I think I should update.

EDIT: Which I did just now, flashed again but it didn't change anything

is like russian roulette :-) have you checked the voltage of the brake-signal wire? It has to have 5V (pullup from processor) otherwise the processor stops during booting. regards stancecoke Brake= vin 4.5V, signal 4.95V Hall= vin 4.5V, signal 4.95V PAS= vin 4.5V, signal 4.95V Throttle= vin 4.5V, s...

I'm afraid I don't have any other places for you to check. Thank you for helping me. I guess buying these controllers from Aliexpress is like russian roulette. You hit or you miss. :? Two recent aliexpress controllers were DOA but the first one I got from bmsbattery two years ago still works like a...

Did this soldering extended legs to pcb and used external 12V input. The output pin gave 4.99V so the chip seems to be fine. OK, then check if the LM317 IC is working properly by applying 20v on its Vin pin and checking if: - The LM317 output reaches 13-15V - The 78L05 outputs 5V properly again (in...

It's 4.5V without sensors connected and with sensors it drops to 4.2V. Well, then I suggest you checking the 78L05 IC in a separate circuit, if possible, to check if the chip can generate the 5V properly. Did this soldering extended legs to pcb and used external 12V input. The output pin gave 4.99V...

What's the reading of the 5V rail with the Hall sensors disconnected? Is it near 5V?

Have you tried to use the BlueOSEC app without the hall sensors connected?

I have. No difference whatsoever. Blu OSEC doesn't read anything. The hall sensor output is 25mA if that's relevant https://components101.com/a3144-hall-effect-sensor.

Can I replace these original S06S mosfets(STP110N7F6) with these ones (HY1707) ?

Hm, what do you mean with Vin? Just a voltage measurement from the controller power cables, when battery is not connected to those. Probably irrelevant. Charged caps, right? If you connect the battery and short red to blue at the display connector, the voltage between the red and the black wire of ...

I flashed with display type: BluOSEC app(for the future) but I don't have bluetooth transmitter plugged in yet. Should I flash again with display type:none for this testing purpose? Does it matter? It's much better to test with BluOsec or Debugging-Mode, as you can read the controller state via UAR...

Hm, can you check the value of the big resistor next to the LM317? There are several reports about trouble with the voltage supply lately. Yes, I can confirm that it's 82ohms Oh btw, I flashed with display type: BluOSEC app(for the future) but I don't have bluetooth transmitter plugged in yet. Shou...

Front motor S06S Battery current max = 70 (as for 7A when battery current cal. a value = 100) Phase current max = 140 (as for 14A when battery current cal. a value = 100) Battery current cal. a = 100 Voltage calib = 50 Undervoltage limit = 164 Whenever I plug in the Hall sensors the 5V rail drops t...

I'm working my AWD setup. Both motors are using OSEC with S06S controllers and sharing a 36V/20A BMS battery. 7A front geared hub motor/ 12A rear DD motor. Can someone confirm that these parameters are ok to flash; Front motor S06S Battery current max = 70 (as for 7A when battery current cal. a valu...

If I want more power to S06S, can I just replace my 36V battery to 48V(52V) and change the undervoltage limit from OSEC? Anything else I need to consider before doing this? Specs at the signature.

With a blocked motor, the phase current limitation will be active. You could check the control state, to be sure. Use the brake of the bike to keep the speed at e.g. 10 km/h with full throttle, then you will see full amps. If not, you have to check your throttle settings throttle_min and throttle_m...

Should the BluOSEC show 15A at the screen when full throttle is applied and the wheel is blocked from turning? Does it ever get to the S06S maximum of 15A? If it should go there mine shows only 11.9A? Obviously then something is wrong here. Either my controller is not delivering the full power or my...

If my twin controller/motor setup (2xs06s) pulls max 25A from the battery and I cannot find suitable (fit inside the battery case) bms for my battery, is it ok to bypass bms and discharge without bms? Can the firmware be trusted to shut down properly? If I just let the controllers shut down power fr...

How to properly test and measure the correct phase current/battery current ratio to achieve the best performance?

The motor is 36V Shengyi Hybrid Brushless DD motor. I don't know why it showed 11amps. Now its back to 1,7amps. I haven't soldered any sensors to the pcb. The controller is S06S from bmsbattery.

If you (or anyone) could suggest the best known working combo I'll order it right away. Thanks see the other thread: https://endless-sphere.com/forums/viewtopic.php?f=30&t=102400#p1497644 https://www.pedelecforum.de/forum/index.php?attachments/1568807983939-png.270389/ 27km/h @630W rear DD moto...

I've driven with the firmware succesfully and without any firmware related problems now in every four seasons past two years. One thing I'm interested is how could I possibly fine tune my setup so that it would be most efficient and also run as fast as it possibly can. I'm now driving max. 27km/h @6...

No update, technical restriction on how "not set" == 0 is handled in eeprom settings. I see no practical use case where 1km/h is a problem that would justify a complete refactoring. So I have to use the Java tool and put 0 to the "Without PAS" -section, flash again and I'm set?

How can I set throttle to 0km/h when NOT in Offroad -mode? The bluosec -app's minimum is 1km/h. Update maybe?

No, please don't do that. It's clearly stated in the wiki as well. For every additional watt you pull out of the 5V rail the linear voltage regulator inside the controller has to !burn! ~5 watts (depending what kind of resistor the poor chinese guy had at hand botching together your very controller...

Hello. Building a 2wd here also. I have s06s with the rear DD motor and KT36ZWS with the front geared hub motor. Both have individual 36V 15A batteries and they will share throttle, PAS and brake signals and also the common ground of the batteries. I already have mounted the main power switch (of th...
