New V2.0 E07-M1101D-SMA CC1101

[haxti]

Hi,

I banged my head on the desk for 2 days now and even ordered more CC1101 modules before I realized, that the new modules seem to have a different pinout. I ordered this one from Amazon: https://www.amazon.de/Ebyte-E07-M1101D-SMA-Transceiver-Transmission-Empf%C3%A4nger/dp/B07P8S9M4W

They are labeled with V2.0 as seen on the Amazon image. I just found a alibaba listing and thought I would let you know: https://www.alibaba.com/product-detail/Cleqee-2-E07-M1101D-SMA-CC1101_62358264393.html

The Board looks identical and the pinout in this listing seems to work so far. I only tried the rc-switch DIP example cause this is the one I need.

Thank you for your work. Please let me know if you need more info :)

In my collection of CC1101 modules, I have one that uses 8 pins and another that uses 10 pins. For these I ended up validating the connections between the connector and cc1101 chip as I was not sure what pin was which. For the 8 pin module I have I did find this data sheet for it that mapped the pins.

Yep this matches with my module and the alibaba listing. Thanks for the datasheet.

It's different to the D-Sun Module on LSatan's image https://github.com/LSatan/SmartRC-CC1101-Driver-Lib/blob/master/img/Wiring_CC1101.png

This issue is just to raise awareness :)

Thank god I am not the only one. I just received the M1101D, trying to make it work with NodeMCU v3 (ESP8266).

I initially wanted to control 303MHz device, but I don't think this can be done with M1101D.

For that reason, I wanted to use them to listen to some other 433MHz devices (chinese motion sensors). I can't get basic example to work - I tried cc1101_New_Receive_method_minimal, got Connection OK and Rx Mode output, but that is it. Everything should be connected correctly - I was referring to attached datasheet and LSatan's scheme for ESP8266.

Before I go on with troubleshooting, am I missing anything obvious?

Ok so to respond to myself: Change the following two settings from 1 to 0 and you should see some output: ELECHOUSE_cc1101.setSyncMode(0); ELECHOUSE_cc1101.setCrc(0);

Still no luck with 303MHz.. I used protocol analyzer mentioned by LSatan himself (https://github.com/LSatan/SmartRC-CC1101-Driver-Lib/issues/38#issuecomment-665694481), but can't see any output at 303.94MHz.

Can anyone confirm that M1101D doesn't work with 303MHz?

Thank you, I have no idea what I am doing. Did you have any luck with 303.94MHz?

[Tomasinjo]

I haven't tried since then. I kind of lost hope after protocol analyzer didn't output anything.

Maybe OP has more info on that? @haxti @NorthernMan54

I used to have devices at 303 MHz, but have long since replaced them with sonoff ifan03 modules. What I don’t recall was if I had ever used a cc1101 to control them.

What I can add to this is that at 315mhz I have devices with a cc1101, running openmqttgateway for transmitting the RF codes to control a fireplace. It will also receive data at 315mhz, but the range is very short ie < 5 meters

Thanks for info. Well I just figured out that my device is not using 303MHz, but 434Mhz. It works well with M1101D.
