Open a writing and reading pipe on each radio, with opposite addresses getting_started sketch, and the likelihood of close proximity of the devices. Set the PA Level low to prevent power supply related issues since this is a Serial.println(F("*** PRESS 'T' to begin transmitting to the other node")) Serial.println(F("RF24/examples/GettingStarted")) Used to control whether this node is sending or receiving * Hardware configuration: Set up nRF24L01 radio on SPI bus plus pins 9 & 53, which are CE & CSN pins */ ![]() *** Set this radio as radio number 0 or 1 ***/ * This is a very basic example of how to send data from one node to another * Getting Started example sketch for nRF24L01+ radios The ABOVE MUST be done manually!!!! So go to the line that says radioNumber = 1 or radioNumber = 0 and set accordingly!! IMPORTANT!!! One arduino must be set to radioNumber = 1 while OTHER arduino must be set to radioNumber = 0 and use this template code for communications tests. and have spare MEGA2560 boards, for similar reasons. make sure to have spare nrf24L01+ modules, in case one of them (or more) is faulty. If anyone has any insight or advice I would greatly appreciate it! I would greatly value your time and may consider discussing compensation for further advice and project help if anyone has any rock solid solutions. At this point in the project, I am almost considering dropping these wifi modules and start investigating others. I have found many different forums across the internet with many users having similar difficulties. I have achieved it using a minimum sketch using just two Unos though, which leads me to believe that the issue is an incorrect pin layout on the Mega or a library incompatibility. I cannot achieve communication using a Mega and an Uno using even a minimum sketch and trying various different channels. Specifically, the "SimpleTransmit-01" and "SimpleReceive-01" The minimal sketches that I ran were slightly altered version of the bare minimum examples sketches found here: I am using the TMRh20 library that can be found here: The wireless modules I am using are the high power nRF24L01 with external Antennas inserted within separate base modules that have a voltage regulator and bypass capacitors. Said data will be logged to a textile and be dumped into a database. The Uno will be setup to capture that data and write it to the serial monitor. The Mega then will display some information on an LCD, light up a few LEDs, sound a buzzer, and transmit some of that data to an Uno. I have a Mega2560 setup with multiple modules that will use its sensors to gather data when presented. Radio.I am having an issue setting up the wireless communication between my arduinos for a work related project. Radio.openReadingPipe(1, thisSlaveAddress) The only thing I'm receiving are a bunch of zeros or wrong numbers.Ĭonst byte slaveAddress = Ĭhar dataReceived // this must match dataToSend in the TX I also tried adding a 100uF capacitor on each arduino. I am using these modules with two arduino mega and a 3.3V external power supply. I want to send data of a joystick from one Arduino to another one. I am having trouble getting this module to work using the tmrh20 lib. ![]() I've been trying to get the Nrf24L01 to work for several days now without much success.
