LowJS Professional error

[ivanpajon]

I bought a license and one ESP32 16MB to use lowjs professional few weeks ago. When I flash my device without --pro --pro-key=MYKEY flags it works fine, but when I flash it with that flags, i see an error in console when I try to connect to it's IDE IP (192.168.0.1 by default).

Also, with lowjs professional, lowsync sync throws a 507 error. So I deducted it's only posible to use through online IDE (I don't know if this is correct).

Using:

• Windows 10
• Node 14.15.4
• Lowsync 1.4.10

[ThomasRogg]

This is weird. So all you are doing is a

lowsync flash --init --pro --pro-key=...

and then you see that error when you connect to the Wifi and go to 192.168.0.1? Do you see the JavaScript example program?

507 normally means that the Flash space is full. You should have 8 MB for files however. How big are the files you are syncing?

[ivanpajon]

I can't access to IDE so I don't see the Javascript example program? Also, I'm not syncing anything so I neither understand the 507 error... I'm using an empty folder initialized with lowsync init.

If I flash my device without --pro --pro-key=MYKEY it works and I can see the webchat example synced in my folder. lowsync sync works in this case too.

[ThomasRogg]

You do not do need to access the IDE to see the JavaScript example program. It runs just like the webchat example, directly after syncing.

I will try to sync myself tomorrow, to see if we simply have a broken image uploaded. Sorry for keeping you waiting... But we will fix this.

[ivanpajon]

I can't see the example program because of 507 error shown above (If you mean to see the files synced in my PC). If I try to access 192.168.0.1 to enter webchat example I can't neither.

Other problem I saw is when I change settings via lowsync settings set wifi.ssid="MYWIFI" wifi.password="PASS" wifi.mode=station wifi.dhcp=client it works until I reset the device. Once I shutdown and start again my ESP32 I need to connect to his wifi and change the settings again. Maybe it can be related... If I flash it without lowjs pro it works properly.

[ThomasRogg]

Things are really weird on your system and I have no idea what is going on. Maybe it is because I am my Mac that I have no problems.

Look what I did here. Please try to follow what I did here and tell me exactly on which step what happens which is different. Please really make sure you have exactly the same steps, exactly the same parameters and so on.

STEP 1: Create empty directory, go to directory

Thomass-MBP:Desktop t.rogg$ mkdir test
Thomass-MBP:Desktop t.rogg$ cd test

STEP 2: Flash new low.js Professional

Thomass-MBP:test t.rogg$ lowsync flash --init --port=/dev/tty.usbserial-14401 --pro --pro-key=<YOURKEY>

To communicate with your microcontroller, connect to the Wifi:
SSID:       low.js@ESP32 CC50E3AB5E30
Password:   ez9gQ8zVGFBG
In this Wifi, the microcontroller has the IP 192.168.0.1

STEP 3:
Here I now login the the Wifi => Works.
Go to http://192.168.0.1/ => I have the example program
Click on the link to the IDE in the example program => IDE works well

STEP 4: Create simple test app
I create a file index.js in the directory test with the following content: console.log("TEST");

STEP 5: Create Project
Thomass-MBP:test t.rogg$ lowsync init
? IP address of the microcontroller on your network: 192.168.0.1
? The local directory that you want to sync with: /Users/t.rogg/Desktop/test
? Enable ES 6 (and more) via automatic Babel transpilation? (if disabled, you wi
ll have to handle this yourself!) Yes

STEP 6: Sync and run
Thomass-MBP:test t.rogg$ lowsync
Fetching file system listings...
Reminder: No password set! Please set one via the lowsync settings set web.password="..." command. Continuing...
? The microcontroller has files in his file system (probably preinstalled exampl
e application), the repository on your PC also. How would you like to continue?
Delete files on microcontroller and copy local files to microcontroller.

Thats it! It works here...

I stopped in Step 3. I have login in to his wifi but i can't access http://192.168.0.1/

[ThomasRogg]

Can you write me the exact output of STEP 2?

I also have tried to follow the steps and flash my device in Ubuntu 20 and MacOS Big Sur with same version configuration (Node, Lowsync, Python, etc) and I always stuck trying to access 192.168.0.1 with same results

[ThomasRogg]

If it does not work at all, on any configurations, it must be the device. Maybe Flash is broken in the higher bytes. I do not know. Do you have another device to test?

Thank you.

[ivanpajon]

Yes I have other device, but I have only 1 license for lowjs pro. Both devices I have works properly with lowjs normal.
