Longs story short.

How do I make a factory reset or hard reset to get the pincode reset on HW420?

Long story. Battery drain and mower powered off completely for few days. Now when I charged it and started it asked for COuntry, language, date and time and then pincode. Right after PIN code was entered it asked for new pincode. New PIN was not accepted for some reasona and there were several attempts I could try but none of the new codes were accepted.

Sow now it got locked and none of the codes are accepted. So How do I reset the pincode?

Could you please send me the logbook?! (Robonect > Service > Download). I will check if I can help you.

Hi Admin!

Thanks for reply. Here comes the xml file zipped, 5MB uncompressed. I tried to understand the contents but it's hard without a handbook. Lots of events and the data is encoded. Let me know if you need anything.

Here are the pins I tried and which potentially were accepted without me noticing it. 2216 is the last known working PIN before it started me to ask for a change.

2216
1755
1808
9608
0785
8279
1756
7783

Update: Something fishy is going with my mower.

By sheer brute force and hours of waiting I listed which PIN (form the list above) was the right one. It was 1755.

Now when I enter correct PIN it goes into this "change PIN loop" something like this

BEGIN
Enter Language
Enter Country
Enter Date
Enter Time
Enter current PIN
if PIN=correct: then
while (true): do #endless loop, I tried to enter 3 different pins
Enter new PIN
Confirm new PIN
Pint not accepted
done
else block for X minutes

Now it's locked OUT again. I Need to list right PIN OUT of 3 I tried to enter.
Do you think it is due to Robonect, shall I try to make a factory reset of Robonect?

Ok, i checked the Logbook. You're right. Your actual PIN is 1755.
The problem with the display is as followed:

During the low battery, the display unit lost his configuration, but the mainboard did not.
Now, the Display unit wants to do an initial setup. Therefore, it asks you for a new PIN. Then it sends the command changed PIN from 0 to xxxx. The mainboard rejected this request, because there is already a PIN assigned.

I saw this issue a few times. Robonect is not involved in it. But i think, i can provide you a solution.

Robonect have to adjust the message from the display to the mainboard with the currently PIN. Then it should accept the change request and the display unit should be happy.

Please give me some hours and I will do my best. I will be back later this night.

I sent you a firmware for robonect. Please install it and try to enter the PIN on the mower itself.

Btw: The logbook is full over error messages. Every two seconds there is an entry, that there was an illegal HTTP Request. It seems, that there is a line longer than 1024 charakters. What do you do every 2 second?

Thanks for explanation and a quick fix. That makes sense. I will try to install it tomorrow morning cause now it is locked for 40 minutes more since I tried another code and that did not work either (remember I tried and I think it changed again).

The log must be full probably because I was playing with setting up MQTT and remove event sending. I need to disable it, thanks for pointing it OUT.

Here's the latest update. Firmware fix works. It allows successful change of a pincode(startup after the battery was drained).

But keep in mind that if you locked OUT your mower then you have to know the right PIN to unlock it anfd then change it.

Thanks admin for your help.

Hello.

I have a similar issue on my r70Li.
My robot is a brand new and before the first init I installed robonect on it.

Then, I start my robot and make the first init. I initialize the code PIN as 0331.

Next, I play with web interface of robonect and I tried to change the PIN on dedicated menu by the same PIN.

Now my robot not reconize my PIN code.

Can you help me with this issue ?

I have download logbook and I can put it in the forum if needed.
