What happened? What did you expect to happen?

hello I just bought an ESP32C3 mini with an SMA CC1101.I configured as follows and it doesn't work. My remote control is a somfy T4300.

How to reproduce it (step by step)

Take a picture of the front and back of your remote.

Ok I know that is a 73400 not a T3400.

Do you have a picture of the pinout for that board? Is it this?

Also can you take a better picture of the CC1101 connections?

[Jeff2405]

I cannot see which pins you have connected to the CC1101. Take a picture of the CC1101 were I can see the connector and the orientation of the board.

EDIT: This is the second one of these branded boards where there was no response from the CC1101 even when everything is hooked up correctly. I do some follks discussing interrupt issues with this board and workarounds to the issue.

Here are the photos If this ESP card doesn't work, which one should I get?

Honestly I love the Xiao ESP32S3. I did a build with it and the S3 chip is blazingly fast with everything. It is very small and the Wifi is spectacular.

As an aside when you are testing I assume you have an antenna screwed into the connector on the transceiver. Is that correct?

[Jeff2405]

yes I have a connected antenna

[rstrouse]

Now that I have the pics I will double check your wiring but I suspect that it is correct. I am so used to folks not wiring correctly.

There is another user with this board having issues and I see reports online that the edge interrupts do not work correctly on it. However, I have another version of the C3 where it does work correctly but there are similar reports online for it.

One think to note is that the C series chips use a RISC-V architecture that may simply be harder for the board suppliers to get right.

[rstrouse]

Here is what I see on your wiring is this correct?

Tr Pin	Color	Func	ESP32
1	Black	GND	GND
2	Red	3v3	3v3
3	White	GDO0/TX	GPIO9
4	Brown	CSN	GPIO7
5	Gold	SCLK	GPIO4
6	Gray	MOSI	GPIO6
7	Yellow	MISO	GPIO5
8	Orange	GDO2/RX	GPIO10

If it is try (without changing any wiring) changing the RX and TX setting to GPIO9 in the configuration then press Save Radio. Then see if you get any frames from the remote.

[Jeff2405]

It still doesn't work even when reversing

[Jeff2405]

I took this file

[rstrouse]

For a C3 that is the correct file. I don't want you to reverse it I want you to set the TX and the RX settings to GPIO9 and hook that up to Pin3 on the transceiver.

[Jeff2405]

I link RX and TX together??

[rstrouse]

You can ignore the GDO2 connection. ESPSomfy RTS will multiplex on GDO0.

[Jeff2405]

I now have the radio not initialized

[Jeff2405]

it's good the radio I put on RX GPIO 09 and ela still doesn't work

[rstrouse]

Did the radio not initialized message go away with that configuration where you have GPIO9 for RX/TX?

[Jeff2405]

no it was a wire that was unplugged

[Jeff2405]

it s ok thank you

[rstrouse]

Are you up and running or are you still having problems?

[Jeff2405]

yes it works I think it's a soldering problem on the esp

[rstrouse]

Awesome closing this!
