Suppose that I can download the firmware on a SD card and upgrade my v3 module this way
Any special location on the SD card -root?

Hi.

Hi.
I have the same problem, I do not know exactly how to search or find the file "ovms3.bin".

I suppose that it is put in the root of the SD, and when it is updated it renames it.

Wifi does not work for me.

Thank you

my model is EU.

Latest production firmware

Latest production firmware can be downloaded from:

http://api.openvehicles.com/firmware/ota/v3.1/main/ovms3.bin

To flash from SD CARD, format card as FAT32 and put that file in root directory. Insert card into the module (when powered on) and wait 1 minute. The module will automatically flash and then rename the ovms3.bin file to ovms3.done, then reboot.

error password

All right. Thank you.

I have another problem, I do not accept the password. I insert the 14 digits of the serial number, but it does not connect.

In the bin file, would it be possible to modify the numbering of the wifi key?

regards

error password

I did have the same problem. Solved by using:
Wifi: fallback to AP mode net "OVMS" password "OVMSinit" after factory reset
Use OVMSinit - Hope it will work for you too!

With the latest firmware

With the latest firmware (which you can update by SD CARD, as previously described), there are now two more ways to do a factory configuration reset:

1] With the module case open, and powered on (either from car, or from USB), remove any SD CARD then press and hold the BOOT button for at least 20 seconds. Then, reboot the module.

2] Put a file 'factoryreset.txt' in the root directory of an SD CARD. Insert the card into a powered on module. Wait 20 seconds.

BOOT button

Hi!
What it is the BOOT button ? Where is he located?

Here is the info straight

Here is the info straight from the User guide.

Module Factory Reset
If you have console command access, a factory reset can be accomplished with this command:

OVMS# module factory reset
Reset configuration store to factory defaults, and lose all configuration data (y/n): y
Store partition is at 00c10000 size 00100000
Unmounting configuration store...
Erasing 1048576 bytes of flash...
Factory reset of configuration store complete and reboot now...

That command will erase all configuration store, and reboot to an empty configuration.

If you don’t have console access (lost module password), you can perform a factory reset of the configuration store using the esptool.py tool from the Espressif ESP-IDF toolkit:

esptool.py
--chip esp32 --port /dev/tty.SLAB_USBtoUART --baud 921600
erase_region 0xC10000 0x100000

Note that after using esptool.py to manually erase_region, you should go into the console and do the ‘module factory reset’ step to properly factory reset.

After either of these two steps, you will be able to access the USB console with an empty module password. When this has been done, we recommend the following additional factory steps should be performed:

OVMS> enable
OVMS# config set wifi.ap OVMS <serialnumber>
OVMS# config set password module <serialnumber>
OVMS> config set modem apn hologram

(where <serialnumber> is the serial number from the label on the enclosure)

Module Factory Firmware

You can switch back to factory firmware with this command:

OVMS# ota boot factory
Boot from factory at 0x00010000 (size 0x00400000)

Or, without console access (lost module password), using the esptool.py from the Espressif ESP-IDF toolkit:

esptool.py
--chip esp32 --port /dev/tty.SLAB_USBtoUART --baud 921600
erase_region 0xd000 0x2000

I read the manual too late.

I will try to solve the problem, it is too big for me, I have to study.

Simpler solution may be:

Simpler solution may be:

1] Format a micro SD card as FAT32.

2] Download this file, and put in root directory of SD card as ovms3.bin:
http://api.openvehicles.com/firmware/ota/v3.1/main/ovms3.bin

3] Create a "'factoryreset.txt" file in the root directory of the SD card

4] With the module powered by USB, plug in the SD CARD, and wait 2 minutes.

After the above, the sd card should contain 'ovms3.done' and the 'factoryreset.txt' file should have been deleted. The module should be running the latest firmware, with factory default settings. You should see a wifi access point OVMS with password "OVMSinit".

Thank you very much, it

Thank you very much, it worked perfect. I already have wifi and I have been able to configure it.

The problem is still, I can not change the password, and I can not do the reboot.

I will keep on fighting

Compiler

Hi. I have used mplab-x from microchip to compile the V2 firmware. Any suggestion what to use for the V3 firmware?
Thanks.
