paneldue via wifi module

[farmer 3d]

hello, i start working on a paneldue connecting via wifi bridge, for me it will be good to work with printer via wifi paneldue anywhere in room, now they seem to be worked only by tx pins, rx not sending packages. paneldue says about connection duet to wifi and nothing more. i using esp-now protocol between two esp 8266 modules. can anyone help in some more information on what packages using between duet2 wifi and paneldue and logical level, may be problem in that.

@farmer-3d nice project. Having the opportunity to display things everywhere without too much wiring sounds interesting.

Although it might be interesting to use the DWC interface instead of building this all on top the serial interface. But this might be too challenging depending on your embedded dev experience.

Does the ESP have a serial interface proxy? I assume this is ESP-now protocol, right?

To test if the serial interface is sending/receiving you can intercept with a simple usb-uart interface connect the RX line. Then you should see the data on the line.

@farmer-3d I think you need to swap the TxD and RxD connections between the Duet and the ESP. Duet TxD should go to ESP RxD and vice versa.

Also for safety I suggest you connect 1K resistors in series with each of the TxD and RxD signals between the Duet and ESP. This is to protect them when one of them is powered and the other isn't. You don't need to do that at the PanelDue end because PanelDue already includes series resistors.

@dc42 tried swap TxD RxD connectors but they wont connect anyway, i add 1K resistors to duet rx tx but its also not help, if now i connecting normally how cable pinouts i get only messages about duet connect wifi and connecting freeze in right corner, no temp or command consoles, also when i disconnect rx pin paneldue give error message, hmm, need to think. i hope its only in packages speed or something with sketch for 8266

@farmer-3d that indicates that the PanelDue is receiving messages from the Duet, but messages sent by PanelDue are not reaching the Duet.

If you connect the PanelDue directly to the Duet, does it still work?

@dc42 if connect by cable - yup all work fine

@farmer-3d looks like you have marked this as solved. Did you find the problem?

[farmer 3d]

@dc42 wops i think its mistake click, nope its still not solved yet

@farmer-3d can you verify the data transmission works? usually it's something like tx/rx swapped or wrong baudrate.

• check if paneldue works with your duet directly
• connect your wifi setup with a loop to your pc, send and receive data
• if those two work reconnect everything

I can't think of something else.

Did you get it working in the meantime? I like the idea of having mobile Paneldue
