Hi not really,

I would like to provide the power of the board via my smartphone. Certabodroid using via the bluetooth interface is to much calbe and devices on my desk.  For Certabodroid I don't need Bluetooth. I use bluettoth to connect the board to bearchess. In beachess I have installed all emulations and my lovely engines.

Dear Dirk

I have to dig in this direction .....

Hello Alain

Which message did you get on the screen? Dirk is right and  i think maybe also need some library to be updates i will double check on Pi_Zero2 we got some units but not yet checked as BT unit.

Try also to do a sudo apt-get update to see if helps in the meantime

All the best

Pietro

Hello Alain Dirk

We did fix for Pizero2 those new chips used in Pizero2W required Bullseye raspbian OS to work (anyhow Raspberry released also a special Buster version (called legacy) to guarantee the compatibility with those new devices end of January.

So we released the BT version for Pizero2W unit image at the following link:

Let us know if all ok

All the best

Dear Pietro

 

Thanks for the update.

I made first attempts . raspi startup is now ok and we are now some steps forward with davinci now launched but frozen at splash screen. (mouse is ok until splash screen)

i used an usb hub with alimentation but perhaps is now an issue dur to my usb hub. i will make Some further tests with different config.

 

Is this image for the usual davinci image of for BT module?

Hello Alain

This is image for BT so does not have graphical interface. It will start automatically the BT transmission from the board.

Just plug the board with otg on middle micro connector on your pizero  and supply on the other or of you have a y otg can supply on the same port.

All the best

Dear all

It's ok with y otg (https://www.amazon.fr/gp/product/B07FC8PYWX) and official power supply in the middle micro connector .

Thanks Pietro and Dirk

I'm happy with this config , connected to bearchess (very useful for quick play and study with the certabo board) or lucaschess .
