Hi,
Anyone know how If can get a USB to TTL Serial Adapter to work with Esp32?
I’m trying to connect a Nextion Display in debug mode but I can’t get the USB to TTL Serial Adapter to work with Esp32, It works with arduino uno and arduino pro mini
Is it even possible to use on with esp32 ?
I have tried these 2 adapters
Thanks,

Hi.
I have only used the second one (the red) using the ESP32-CAM and it worked fine.
I haven’t experimented with a regular ESP32.
Regards,
Sara

Hi Sara,
Yes I have seen many tutorials and information about the Esp32-cam and these devices but none for a regular esp32. I have the (doit devkit v1 esp32) and just can’t get it to work. I have look everywhere but no luck :(.
But thanks for replaying.

Hi Guillermo,
This video may be helpful to you. Video has some gotcha’s; working with hardware UARTS on the ESP32.

Hi William,
Thanks for the link, Unfortunately is not what I’m looking for it. I’m familiar with changing the pins for the serials.
But have not been able to have the esp32 communicate in the nextion display in the editor in debug mode.
Appreciate your imput

Hi Guillermo,
Are you using the latest Nextion Display library?
May want to check version of Nextion Display library; earlier version did not work with the ESP32.

William,
I had seen that info, In fact that how I started but now I’m using no library at all.
I found the info I needed, I had the wrong idea about the debug, but everything is good now.
in case someone else need info about it here is the link
Thanks
Guillermo
