Maybe I'm missing a pull-up or a pull-down resistor somewhere. However, I'm hoping the OTA that one can get for little effort within the Arduino framework (see post immediately above) will do the job, especially since it's already so well integrated with the Arduino IDE. Someburner's approach was quite sophisticated (amazing work!), and one of the benefits of that was the OTA updating. I think I may try doing the same, with the hope of leaving GPIO2 as a secondary serial Tx in case it's beneficial to have for debugging. ![]() It looks as though someburner connected DIO0 to GPIO5. LowPower.However, did you have to do something to activate the SPI functionality of the HSPI pins? Are you doing Serial.flush() //make sure all serial data is clocked out before sleeping the MCU ![]() radio.receiveDone() //put radio in RX mode check if something was received (could be an interrupt from the radio) tHighPower() //must include this only for RFM69HW/HCW! Radio.initialize(FREQUENCY,NODEID,NETWORKID) ![]() #define ENABLE_ATC //comment out this line to disable AUTO TRANSMISSION CONTROL #define IS_RFM69HW_HCW //uncomment only for RFM69HW/HCW! Leave out if you have RFM69W/CW! #define ENCRYPTKEY "sampleEncryptKey" //exactly the same 16 characters/bytes on all nodes! Match frequency to the hardware version of the radio on your Moteino (uncomment one): At some point a was using the Texas Instrument CC1101 RF module with the ESP8266 which gave me some results after using the SmartRF04EB debugging device in combination with the TI smartRF Studio 7. #define NODEID RECEIVER //change to "SENDER" if this is the sender node (the one with the button) Arduino ESP32 core LCD driver RFM69 OOK driver. #define RECEIVER 1 //unique ID of the gateway/receiver #define NETWORKID 100 //the same on all nodes that talk to each other Any ideas? So basically I want to make a 868 Mhz sniffer with my Arduino Uno and RFM69HW. I use the below sketch but it does not catch any signal from my thermometer. Problem is that obviously I don't know what is the NETWORKID for example. ![]() Trying to receive the 868 Mhz signals from my Buienradar br-1000 station with a Hope RFM69HW tranceiver.
