"Repeater_cc1101.ino" in "Rc-Switch examples cc1101" only received and transmitted the first time then afterwards it has been unresponsive.

[AhdHahn]

Has anybody worked with "Repeater_cc1101.ino" ? I tested in "Rc-Switch examples cc1101", "ReceiveDemo_Simple_cc1101.ino" and "SendDemo_cc1101.ino" on Arduino Nano ATmega328P it worked fine; however, the Repeater_cc1101.ino" has a problem. It only worked the first time. The first time it both received and transmitted afterwards it has been unresponsive.

hi, i will change and improve the sketch again. it was one of my first additional skits for rc-switch. now it can be simplified and made shorter. regards

[AhdHahn]

Hello LSatan, Thank you very much for fast reply. I tested the "Repeater_cc1101.ino" on NodeMCU-32S ESP32 it worked fine; however; "Repeater_cc1101.ino" does not work on Arduino Nano ATmega328P. (tested by SmartRC-CC1101-Driver-Lib_V2.5.2) Thanks.

[LSatan]

Please check this and give me feedback.

Hello LSatan, The result shown

Received 13964736 / 24bit Protocol: 1 Delay: 393 Transmit Receive

only the first time afterwards it has been unresponsive.

(tested on Arduino Nano ATmega328P) Thanks.

[LSatan]

hey sorry saw the answer too late I'll take care of it. which cc1101 module do you use?

[AhdHahn]

https://www.analogread.com/product/200/cc1101-wireless-module

I use the CC1101 module. I connected the CC1101 module with ATmega328P and NodeMCU-32S ESP32 as your guide in SmartRC-CC1101-Driver-Lib-master\img folder.

( "ReceiveDemo_Simple_cc1101.ino" and "SendDemo_cc1101.ino" on Arduino Nano ATmega328P it worked fine; however, the "Repeater_cc1101.ino" has a problem on Arduino Nano ATmega328P.

"Repeater_cc1101.ino" on NodeMCU-32S ESP32 it worked fine. )

[LSatan]

hey I tested the old and the new variant on the nano again! It works without any problems! I use the same cc1101 module. I don't know what you're doing wrong. please check if you have swapped GDO0 and GDO2. this is the most common error.

[AhdHahn]

Thank you very much LSatan. I am ordering a new cc1101 module. I will let you know the results when I have tested the new one.

I got 2 new modules. (the 2 web links above) I tested them both with the "Repeater_cc1101.ino" on Arduino Nano ATmega328P. They both worked.

I ran into this very same issue with the repeater sketch (Receive and transmit works, but after first transmit no new messages can be received). I am using this module from aliexpress.

I seem to get this to work reliably by toggling Rx and Tx mode a couple of additional times, eg instead of:

mySwitch.send(mySwitch.getReceivedValue(), mySwitch.getReceivedBitlength());
  
ELECHOUSE_cc1101.SetRx();
mySwitch.disableTransmit();
mySwitch.enableReceive(pinRx);

Serial.println("Receive");
mySwitch.resetAvailable();

I do

mySwitch.send(mySwitch.getReceivedValue(), mySwitch.getReceivedBitlength());

mySwitch.disableTransmit();
ELECHOUSE_cc1101.SetRx();
ELECHOUSE_cc1101.SetTx();
ELECHOUSE_cc1101.SetRx();
mySwitch.enableReceive(rxPin);

Serial.println("Receive");
mySwitch.resetAvailable();
