Send AT Command va UIFlow

[TheAlphaGhost]

Hello,

i have a M5Core device.

Yes, i switch from TX23 -> to TX17, and RX19 -> to 16. Thanks for this tip.

But, now i have a last question, see screenshot below.
I Arduino i write with Serial2.write(...) the Hex. How can i do this in the UIFLOW ?!

Please see screenshots...

Hope you can help me, with my last question...

Hello @TheAlphaGhost

the block you are using actually writes a string "0xFA" but you want the raw hex value.

I see two options:

• convert the hex values into decimal values, then use a UART - write raw data block or
• try an Advanced - Execute code block with: uart1.write(b'\xFA')

Note: untested as I don't have the required hardware.

Good luck!
Felix

Hi Felix,

Vielen dank für Deine Unterstützung ! Sprichst du deutsch ?

Thanks for your help. I will try both options, and will send a feedback here.

Mhh, still not work. Don't know what's wrong...

Hello @TheAlphaGhost

I think the problem is now with uart1.write(ServoID). Eg. sending values from a variable. When I try this, the receiving end gets a string instead of the hex value.

Unfortunately I am not a Python expert - I tried a few things but nothing seems to work. Sorry about that.

Thanks
Felix

I wish the blocks were in English so I don’t have to Google Translate it all 🤣🤣🤣.
Kidding though. I can tell by the block colors what’s going on. Nice job fixing it!
