New firmware V3

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 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.

thank you very much.

regards.

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

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

Thank you

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:

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".

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