@rintaro pls check the attached FW for 300RI, and upgrade it by Configuration-->Upgrade Firmware, and then pls check whether right data send out or not?
pls note:

• 300RI data analysis only supported by [python driver] (https://developers.aceinna.com/devices/connect) eventhough it can also be upgraded by NAV-VIEW,

• after connected by ANS web, 300RI will not send UART data at first(for output data rate is 0hz defaultly), so still need to change seting--ODR to none 0hz value.

  Wait your feedback.

@cek
Thank you for your quick support!

"the installation" means installing VG AHRS 1.0.1 for OpenIMU300RI.
Before installing it, the IMU doesn't output any data such as acceleration, gyro.
After installing it, the IMU has started to output data but all the data are 0.
I'm sure that I downloaded VG AHRS app for 300RI.

Anyway, I'll try your instructions. Thank you!

@cek

I followed your instructions, but the problem still remains.

How I updated firmware

• I downloaded your firmware(5020-....._plan.bin) and rename it as new.bin
• I updated it by python-openimu driver.

~/hoge » openimu
This is openimu main routine.

How it looks now

• I executed server_start
• I opened web interface
• I changed packet rate via SETTING -> Unit Configuration

Configuration looks good because openimu-driver says as follows.

>>server_start
>>Successfully Updated

But no data are shown.
I also tried baudrate 57600 but nothing changed.

I'm waiting for your advice!
Thanks.

P.S. As I mentioned, I pushed "Software Reset" button in NAV-VIEW when I was trying to figure out why I couldn't get any data.

"Before installing it, the IMU doesn't output any data such as acceleration, gyro."
when got it from plant, it should be working well. but your unit configuration not right, so after you received before installing IMU, what actions did you do?

@cek
Another colleague who bought this IMU says that he saw some numeric data on NAV-VIEW,
but at the moment I received it, it didn't output any data.
I'm not sure what the missing link is.

Is there any way to completely refresh it to plant shipping state?

May be already damaged by misoperation, we are trying to find solution for you, pls wait.

@cek
Sure. I wait for your solution.
Thank you for your job.

@cek
Thank you for your efforts.
Can I ask when you could give me what to do?

still find solution, still need more time, I can't reproduce your phenomenon now.

@cek
Thank you for quick reply. I understand.

@rintaro you need to do:

• send commands to 300RI to lock one sector of the Unit, by UART.
  

• power off and on, running with python diver and connected by ANS web page. maybe you need to change the packet rate, and click play button. check whether some data output.
  

• after connected by ANS web, pls upgrade to below app, then power off an on, check how the status is in your side.
  

@cek
Thanks for the instruction.

I'm not sure that "55 55 4C 45..." worked or not (is there any way to confirm the command was accepted?)
But anyway I can see all-zero-data on web interface now.
Is this your expectation?

@cek
What do you think will happen if I push "Algorithm Reset" button on NAV-VIEW? Is that a bad idea?
(I've never pushed it)

@rintaro if it worked and will give feedback, if not you need change the baud rate and try again:

SW/Algorithm Reset generally no problem, cannot lead output data 0.

I still want to know what other actions you had done? e.g. send some commands to IMU.
for the CAL/CONF area may be already broken, but generally you cannot break it only by boot loader(boot loaderworking fine now) except some special commands received. or it can be recover well.
so i need time to find solution to recover your CAL/CONF area, working on it.
if you have other more information, pls let me know.
