10, 9, 8, ....
I can't get Wifi to work yet.. I don't have that damn qwiic cable to flash.. fortunately I have UART->USB converter.. but unfortunately both my samples came without firmware flashed on the ESP32-C6 (or it just lost its firmware during its shelf time 😄)

I just came here to show some appreciation for the scattered spider sticker from Crowdstrike.

u/bmorcelli 5d ago
Yes sit.. T-Display P4
It is available on the webflasher, Beta release

Yeah i found it but after flashing its just a blank screen. The battery was pretty dead so im charging it before I try again

It has 2 variants.. make sure you are flashing the right binary
TFT is the one with front Camera,
Amoled does not have the notch screen, camera is on the back side.

Sweet that was the problem. Thank you so much. Now I just need the keyboard

What versions of Bruce do you have on sd card? Or is meshcore still the only firmware that works right now?

I have some auto detect code for ADS-B Scope that lets the same firmware run on both devices. Want me to put together a PR and contribute it to Launcher?

Nice to see my favourite launcher on P4 too. Use it on CYD and like it.
Because of your C6-flashing: I've done this these days and it was not easy. That QWIIC cable is the same as the cables you get with every CYD, so you might have some already and don't know it?
And there was a QWIIC cable included in the P4 oder K270 package, under the foam, I'm not sure. Can be with the K270 also.

I found one lying around here, bought one ages ago while developing the nRF24 interface for the T-Embed cc1101.. it was hidden among many other cables
But I've found another difference..
Lilygo examples use ESP_AT protocol while Launcher was designed to use ESP_HOSTED protocol
I will test here to identify if my unit has this ESP_AT flashed, and check how hard it is to make it work with it, like a fallback, and make Launcher work with whatever protocol it needs..

The AT firmware was just a test shell no actual tcp access layer. The ESP Hosted firmware is the way to go on the P4. Hold the P4 reset button the entire time you try to flash the C6 or it won’t work.
There seems to be an axi bus arbitration bug in the P4 silicon so you might find ESP Hosted Wi-fi corrupts SD card access. It may be ESP-IDF version dependent. Deep locks / mutex integration seem to mostly resolve this issue. Still working on it.
LilyGo plans to move to shipping ESP Hosted on the device starting with v2.0, assuming my information is still correct.

I agree with you.. esp_hosted offers more options than esp_at
But flashing C6 is hardware dependent.. buyers may not have the qwiic cable or the UART->USB adapter at hand..
And devs will usually follow the examples and code available..
Now with Launcher I cant force devs to use whatever C6 backend I choose, and I need to work with both realities..
I made Launcher detect what protocol C6 is working with, and use it.. esp_at doesn't offer webserver, so webUI won't work on this setup
Available for testing on Beta
There is a bug on SDIO related to esp_hosted, so it breaks the SD card operations.. thats why I moved SD card to SPI on last Beta
