Esp-Wroom-32 CC1101 (8pins)

[BeniIgle]

Hello there, could someone please help me to connect and give me a code example? i have my esp-wroom-32 and my 8pin cc1101 (EO7-M11010) and i want it to receive 433.92 mhz signals i tried every single connection and code in the internet and no one worked. Im thinking that the problem could be the power(? i dont know what else to think or to do. even tho sometimes it puts connection ok, i receive random data every second and when i press my remote buttton, i dont receive nothing but the random codes

check your data sheet should be something like this one : https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjE7_TwyNODAxU8Q6QEHcx3ACAQFnoECBcQAQ&url=https%3A%2F%2Fwww.ebyte.com%2Fen%2Fdownpdf.aspx%3Fid%3D165&usg=AOvVaw0_nU7dTRDlzfCF9m1j1tQn&opi=89978449

then you need to setup the pins with this functions, before init:

ELECHOUSE_cc1101.setSpiPin(18, 19, 23, 5); ELECHOUSE_cc1101.setGDO(2, 4);

any chance you made it work ? got the same modules, and trying to make them communicate ! GS

@slater0013 May I know what are you trying to accomplish? I manage to get the module to replay signals captured from an RF remote, is this what you're attempting as well?

Just trying to build a long range powerpoint remote here :) previous/next buttons

[smolbun]

Are you building one from scratch? Or is it an existing powerpoint remote that you're using?

[slater0013]

Building one from scratch ! I was looking for a project idea to start digging into the wireless modules :)

[smolbun]

You could take a look at the example for tx and rx and set the pins accordingly for your ESP32.

ELECHOUSE_cc1101.setSpiPin(SCK_PIN, MISO_PIN, MOSI_PIN, SS_PIN); this should be called before ELECHOUSE_cc1101.Init(); As for ELECHOUSE_cc1101.getCC1101(), it seems to always return true for some reason.

Hello there!!

When attempting to run the minimal receiver example from the Arduino library for the CC1101 module, I encountered several compilation errors and warnings. These occurred in the ELECHOUSE_CC1101_SRC_DRV.cpp file.

Steps to Reproduce:

• Opened the minimal receiver example in the Arduino IDE.
• Compiled the code for my esp32.

Error Messages:

The specific errors and warnings I encountered are:

ELECHOUSE_CC1101_SRC_DRV.cpp:149:3: error: this 'while' clause does not guard... [-Werror=misleading-indentation]
   while(digitalRead(MISO_PIN));

ELECHOUSE_CC1101_SRC_DRV.cpp:150:2: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the 'while'

cc1plus: some warnings being treated as errors

I would appreciate any help in understanding and resolving these issues.
