data send from one node to other node more than one time while doing rfm69 communication

abt last edited by abt

When ever i am sending data using serial port from one to another. Data gets printed on serial port 2 to 3 times. I am using arduino uno. I am referring https://learn.sparkfun.com/tutorials/rfm69hcw-hookup-guide/all#res code.Here for Node 1 same code and for Npde 2 just swap value of MYNODEID and TONODEID.Here i am using 868MHz that i have already changed in my code.

@NotYetRated Hope you'll find good uses and a fun time while building your sensors.

@OldSurferDude no offence but rtfm #define MY_NODE_ID 3 is all you need to set predefined node id's, change 3 to any number from 1 to 254, it's worth having a spreadsheet with assigned ID's to avoid doubles, or at least write ID on the node itself. If you ommit above define Mysensors store ID in eeprom after it gets autoassigned by gateway/controller on first start.

Quick Range Check on the WIO-E5-LE. The LE version uses only the low power PA, +14dBm max. Using the default settings except for 915MHz #define MY_SX126x_FREQUENCY (SX126x_915MHZ) #define MY_SX126x_LORA_SF LORA_SF7 #define MY_SX126x_LORA_BW LORA_BW_125 #define MY_SX126x_LORA_CR LORA_CR_4_5 I get about 190 meter range, just walking around the neighborhood, line of site except for some trees and power lines. No tuning on the antenna. Just using a 77.9mm wire. Not as dramatic as some have achieved with LoRa radio's, but plenty good enough for my house and yard : )

Hallo! Ich habe gerade meinen Aduino Nano mit einem GY-BME/P-280 verbunden über SPI verbunden. Im Sketch habe ich nur die PINS geändert und zwar auf: #define BMP_SCK 13 #define BMP_MISO 12 #define BMP_MOSI 11 #define BMP_CS 10 Ich bekomme aber bei der Ausgabe am seriellen Monitor nur "Hyroglyphen" zB 5��,�lh��}��'�O8��m�h,� Mit einem anderen Sketch funktioniert der Sensor einwandfrei. Auch mit einem anderen Nano dasselbe Ergebnis. Hat jemand eine Idee was das Problem sein könnte? Zusatzfrage da ich in C++ nicht so firm bin: Könnte es sein, dass MY_DEBUG oder MY_RADIO_NRF24 das problem verursacht. Was machen diese Definitionen eigentlich? Grüße
