It seems there is a sync command failed, please power on the device again if you encounter the firmware upgrade issue through web.

Try to refresh the page. The automatic connect check may be past.

If the green LED always flash, when it powers on, it means the device is in bootloader. We may do some steps to get it back.

1. Send JA command to switch to app mode. The raw command should be 0x55, 0x55, 0x4a, 0x41, 0x00, 0xf5, 0x9d

2. Upgrade firmware with command line.

Steps to upgrade OpenRTK330L_GNSS_RTK_INS_v23.05.bin

• Power off and on your device.
• Open python driver with specified parameters. Webserver_Win32_2.5.0.exe -c {the actual COM port} --cli. Wait for the device connected.
• Use command upgrade {the firmware path}
• Wait for the upgrade progress finished.

Please take a look of the page https://developers.aceinna.com/devices/connect, and try to use python-openimu to connect.

Send command 55 55 70 47 00 5D 5F with hex format in baudrate 57600, to check if you can get response. If there is any response with serial number, please try to upgrade the firmware again.

Here is screenshot with the new bin.

The INS app may take more time than other apps while connecting, and to make the connecting more fast, it is better to assign startup parameters when you use webserver.

The command looks like as below,
.\Webserver_Win32_2.3.2.exe -b {baudrate} -c {com port}

Please also try to send pG command with a serial port debug tool to make sure the device can response its device info.

If the INS app is developed by you ,is there any data output when you use a serial port debugging assistant tool？
You could also try to send command 'pG' in a serial port debugging tool to confirm if the device could response its device info.
The hex command is 0x55 0x55 0x70 0x47 0x00 0x5D 0x5F

If there is no response, you should check the source code.

1. Which INS app you are using? Is it from our official release?
2. If the INS app is developed by you, could share it to public in app center?

Luke, there are some suggestions.

1. Flash the backed up firmware to the device with ST-Link again.

2. Modify the packet rate, we think the packet rate may changed to 0Hz.
   a) Connect device with python driver https://developers.aceinna.com/devices/connect
   b) Update the packet rate on page. https://developers.aceinna.com/devices/record-next
   
   

3. If there is still no packet data output, please leave the serial number of the device, we will try to send the whole bin to you.
