LILYGO T-Embed ESP32-S3 CC1101 not detecting signal
Hardware
ESP32-S3
Firmware version
v2.4.7
Application version
v2.4.7
What happened? What did you expect to happen?
When scanning frequency using the web interface, no signal detected when pressing buttons on remote. (RSSI remains blank). Have tested hardware using BRUCE and was able to detect a signal on 433.420MHz. Have confirmed blind motor is Somfy.
How to reproduce it (step by step)
Configured pins as per https://github.com/Xinyuan-LilyGO/T-Embed-CC1101

Oh that is no good I am building one on that platform to replace my other one powered by USB. When building that one I had same issue. Solution was to correct wire the CC1101 to the board. I mixed up 2 wires after adjusting so it matched, all was well.

@watgaan do you mean the T-Embed arrived incorrectly wired? Or were you building from scratch? The one I bought already had the CC1101 wired in - wondering if I need to reassemble it
I was building from scratch so the CC1101 had to be wired, I ended up have 2 wires mixed up, after correction it worked fine. You can check in settings if the GPIO match how your device is wired (but you most likely already did).
@brycetg Have you ever been able to fix this issue ? I'm also looking into using this device instead of manually building one on my own as I'm not very good with wiring!

Unfortunately not
@brycetg Hi! If you look at the schematics here https://github.com/Xinyuan-LilyGO/T-Embed-CC1101/blob/master/hardware/cc1101-shield.pdf, the switches SW_1 and SW_0 on the HPD24A2 chip has to be set at 1 in order to be able to use the 434mhz signal
I guess they are at 0 by default and there is no way to change the settings currently as this is hardware specific. On the T-Embed CC1101 page we can see that the chip are set as follow:
#define BOARD_LORA_SW1 47 #define BOARD_LORA_SW0 48
@rstrouse It would be very nice if this feature could be implemented as the T-Embed CC1101 makes a super compact and nice package!
I was also struggling to get the firmware to play nice on the T-Embed CC1101 Plus over the past several days. Or any other ESP + CC1101 hardware combo for that matter. Tried ESP32 Dev, S3 Zero, C3 Super Mini. None of them works. Managed to get the pre-built loaded, and to make the "Radio not initialized" go away by swapping pins. However, the contraption neither receives, nor transmits any signals (as verified on the Bruce running on T-Embed). Tried different CC1101s, even from different vendors. Tried swapping pins. But no joy!
Badly needed this for my new roller blind installations. It would have been nice if a pre-built unit or a kit with matching components were available. But for now I guess I will keep fiddling with it hoping it is a minor mistake that I am overlooking.
