I have two other "analogPins" which are endstop switches. print((char*)buf);That only works if buffer was really a null terminated char array (a cString) - which is not what you have there. But every example i see only sends strings. My latest idea was to reduce the size of the structure I'm using to send the data, so take floats and use int16_t instead, saving 2 bytes of data per field. I am working on a LoRa based project for transmitting data between two LoRa devices. The code I'm using comes almost directly from the examples provided by Arduino. I have a GPS on my transmitter and want to send the lat and lon to a receiver. send((uint8_t*)txRTCM,250 ); but it didn't work with this type of string can anybody help me please Best regards. So far so good. 0MHz, Hi guys, So i have a problem. Unfortunately, when I try to run code like char[100] data; void setu Hello, I have two identical lora radios (RFM9x) one is connected to an arduino UNO and one to a Raspberry 3b+ I'm able to send packets from the Arduino to the raspberry but but for some reasons I'm not able to make th Hi, I am newbie, please bear me 🙂 I am following this client server example of RadioHead found in its library RadioHead: RadioHead Packet Radio library for embedded microprocessors , I have few questions if someone can help me: I do not see server or client address so how server and clients are sending messages? We can see code "while (!Serial) Hello I have a "custom" Arduino zero board with a lot of extra stuff on it. Please read and follow the instructions below. 🙂 LoRaDumpRegisters. I am able to get the board back by uploading a blink code with verbose upload but my below code doesn't ever Arduino IDE 2. When the button is pressed I want to move the servo. The RF95-server sketch uses the led=9 to show the status. I want my Feather to relay serial inputs to radio and vice versa. h> #include <DallasTemperature. Modem config defined as RH_RF95::Bw125Cr48Sf4096. I am developing a device transmits bme280 (temperature, humidity, pressure sensor)'s data to another arduino using rfm95 lora shield. I got two 868 Mhz RFM95W LoRa Radio Breakouts from mouser. Specifically for the length parameter: Parameters [in] data Array of data to be sent [in] len Both Dragino shields are connected onto Arduino Mega. when i open it, the code doesnt seem working neither verify nor upload. The GPS on Hi, I am Florian from Germany. /* SimpleSend This sketch transmits a short text message using the VirtualWire library connect the Transmitter data pin to Arduino This method can be used to send and receive numeric values or integers over a short distance from one Arduino microcontroller to another. IT is basically similar to Adafruit feather M0 with the same radio on. Hello all, I'm attempting my first LoRa radio client/server and, while the basic Adafruit radio example works fine (it's not a server, just sends a message), the RadioHead client example I modified does not. println("recv failed"); RH_RF95 class does not provide for addressing or // reliability, so you should only use RH_RF95 if you do not need the higher // level messaging abilities. I will then have another uno with a rfm69hcw and a rgb led. I would like to read a temperature sensor in 1km distance by radio for example. I'm using RadioHead library for LoRa - RF95. edit(1) when i Hello, I am using a two SAMD21 Pro RF boards to communicate and drive a stepper motor. init() method returns true. . g driver. I have tried using wire antennas (cut to the right size), and larger RP-SMA antennas, which have little Hello everyone, new to this forum, nice to meet you all. On the receiving side, today you are getting 3 bytes with. example sketch is here: I have the pulse counter working with my Uno using this sketch //Detect how much water has passed the meter. Pycurl is used for HTTP. Printing the message doesn't print anything, and strlen gives 0. Assuming int temperature: rf95. h> #include <OneWire. Nico_del_Bernardo November 18, 2018, (RF95) radio network and send them to the * serial port for monitoring or debugging a LoRa network. Testing revealed that the Tx and Rx unit would work perfectly at a range of 2 meters but more distabce than that message is "send to wait failed". I would like to send 2-digit numbers from one to the other and drive the stepper motor based on the values sent. h> #include <String. would be to modify RadioHead RH_RF95. My setup is Sparkfun/Arduino Pro-micro 3. Hi everybody, I reckon that essentially replaces "data" which was Hello world in your rf95. I'm hello i want to send data from LORA device to my java server that has IP an port number for my university project. Printing GPS and Transmission info on Serial works perfectly. So far I've gotten the GPS working, but cannot get Demos de Arduino con LoRa. i want to send a "1" every time a pulse from sensor (on pin2) come's in. org. I can send packets to the RF95 and receive them fine but when I send a packet the from the RF95 to the 1310 I get nothing. send(altData, 16); delay(10); rf95. Things are working wonderfully in testing, but I'm about to start writing some more robust code and I have a question about some documentation I ran across. receiver use arduino and lora rf95. I just want to "clone" the termostat signal instead. Development Tools. h> #include <dht. I still don't understand though why strlen() has to be used in this situation instead of sizeof() It depends, of course! strlen() tells you the number of bytes of useful C-string data in the buffer (minus the zero terminating byte). in the rf95. It usually stops after the line "Serial. I have tried modifying several sample files. After two seconds, it should print out the sensor value for the accelerometer and transmit the data // imports library #include <Arduino. I'm wondering why it stops after a while. Using Arduino. However my real problem is on an Arduino Due that i have set up with a Lora_BEE I am using RadioHead Simple LoRa Client to connect to the Dragino LG01-N Gateway I am in the EU so the frequency i use is ISM 868 Hi all, I am trying to use the RFM95W chipset from adafruit with my nRF52832 feather. Mine is a fixed message I am trying to transmit packetized audio file that is stored locally on my pi through LoRa to another set. h> #include Hi there, I'm struggling with the RadioHead RM95 Arduino library. Sure, sometimes you want to talk @kiwiwiki, you might be interested in some code I have been working on, its purpose (I hope) is to provide a clear method of sending and receiving numbers over LoRa. I managed to make them working as transceivers a few days ago but today they won't operate until i open the serial monitor for each COM. It becomes very unstable after 1-2 weeks of continuously running. waitPacketSent(); Serial. send doesn't like receiving either the buffer or sendlen, but as I've copied your code exactly complete with variable types, I don't understand I think it might help. byte bGlobalErr; char jsjskat: Anyway, after looking into the RH_RF95 library, I noticed that this constructor needed a software serial parameter. waitPacketSent(); uint8_t buf[RH_RF95_MAX_MESSAGE_LEN]; uint8_t len = sizeof(buf); Hello, Welcome to the Arduino Forum. My intended use is to transmit water pressure numbers from the arduino at the pipe to the arduino at my display. org is not currently supported. I am learning about using the very cheap $2 433 Mhz wireless transmit & Receive eBay boards. I followed the instructions and got it working (hello and other strings). However the receiving end never gets a message. Hello, i'm using two microcontrollers RFM9X Lora adafruit M0, i want to send a string showed in the figure, but i can't send it. h library but was unsuccessfull so I am trying the Radiohead library. Telegraph Key. I have an Arduino mega with a LoRa Shield and i can't use SF12, up to SF 10 is fine tho and i dont know why. but when i do this it is not working after 1 pulse: /* Simple Pulse Counter Counts digital pulses fed into pin 12. For my project, i have two adafruit feather 32ua lora modules and i am using arduino ide to program them. println("Incoming Message"); I am having trouble sending a value and then testing for that value after it is received. Here the variable that the value is assigned is an unsigned 16-bit integer, hello, I am looking to use the adafruit rfm95w(Adafruit LoRa Radio FeatherWing - RFM95W 900 MHz [RadioFruit] : ID 3231 : $19. h> #include <Wire.

Its an Adafruit Feather Hi there, I am trying to read a 32 byte array into python and not getting it to work properly I feel I am really close but its just that last little bit where its not working I am receiving a 32 byte message from a lora transmitter on one board and receiving on another then I want to send the received bytes into python the wireless send & recieve works great but I can't get Also I modified the line rf95. I've not in Dear forum, I am trying to build a module that collects GPS data (among other things) and sends that data to a receiver via LoRa radio transmission. 7 from arduino. 111 for humidity and temp. send() that the unsigned byte buffer includes the special terminator character '\0' which is not included in a string's reported length but always exists if the string was generated properly Context I am trying to write a sketch that uses two different functionalities: Some environmental data is measured by 8 BME688 sensors of a BME688 Devkit (an Adafruit Feather compatible shield) and is further processed using a sensor fusion library (bsec2 library from Bosch Sensortech) which allows to perform a classification task between different kind of gases. waitpacketsent(); From a lot of googling I suspect i have something todo with the Good Evening Guys, I am working on a project where I'd like to send recorded sensor values using LoRa. I've tried adding null terminators and changing the size of the message to send. h" In this project we will connect 6 Flex Sensors with the Arduino and send their values wirelessly. I am trying to add a hopeRF RFM95 module to the board. The project that I'm working on uses a multi-hop system (RH_ROUTER) for sending data. abidva sufhgr zhf hbuc dzddyi symslgy ofi lzlhm lyp bmz
