mopi configuration - Error Message (mopicli. Expected at least MoPi firmware version 3.05, got 0.00 instead.)

[RockSoft]

I have just purchased a MOPI for my raspberry pi zero and have installed all the software components, using the online instructions. I start the MOPI with out any problems 'Green LED is on' and both yellow LED's are on and stable. I have hooked up 2 9v rechargeable batteries.

I am able to ssh into the raspberry pi zero without any problems. I am then trying to run the topi configuration tool as per 2.3.2. Using the Configuration Tool on the Pi on the online user guide.

When I type sudo mopi in the terminal window I get the following message:

sudo mopi

/usr/sbin/mopi: /usr/sbin/mopicli not working; installation problem? (mopicli. Expected at least MoPi firmware version 3.05, got 0.00 instead.) Usage: mopi [-h(elp)] [-d(ebug)] [-v(ersion)] [-l(og entries)]

Any assistance you can give would be gratefully received.

Hi, MoPi uses the Pi's i2c bus, which, on the zero has to be soldered in... Did you do that? Cheers Hamish

I have soldered 40 pins to the pi zero board and the mopi is stacked on to those pins. I also have external power taken through the GPIO pins from a second raspberry pi zero. I have attached a picture of the setup. I've just followed the online instructions that you have on your webpage. so haven't done anything different. There raspberry pi has been used for other things, but the I2C is enabled through the raspberry pi configuration. I've attached the raps config for your information

just ran: sudo mopi -d and it went into the configuration. running the command without debug on -d I get the same error as before

[hamishcunningham]

For some reason the i2c communication is not working, at least partially

What happens if you try and save config to the device?

It says mopi has been configured, but when I go back into the config using the -d option the settings do not seem to have been saved. When I go into local config the following is shown (see picture) My batteries have also died now, so won't be able to do any more on it until they have recharged :( Are they supposed to drain while there is an external power supply?

[hamishcunningham]

Do you have anything else that uses i2c that you could use to check the GPIO header?

[RockSoft]

hi Hamish - I'm afraid I do not have any other hats I can attach to the raspberry pi. However, I have tried attaching it to another pi zero, in order to see whether it might be a local GPIO issue but got exactly the same error message. Could the MOPI itself be faulty or is there another way of testing the GPIO pins without a hat?

Any update on this issue? The following is a log from today

My apologies, but I don't have a zero to hand and can't try to replicate here :-(

I can offer you a refund?

[RockSoft]

Ok. I'll take a refund. it's a shame its got great potential.

[hamishcunningham]

fair enough

btw I'm not implying that I think the MoPi is definitely at fault here, just that I don't have time to try and duplicate the problem :-(

please email me the sales invoice and your account details

thanks, and sorry I couldn't help!

Hi Hamish,

Not a problem and I fully understand.

Oops don't want my account details in gitHub. I'll send you a separate email. Thanks Peter
