PIzeroW + RFM69HW + arduino node connection problem
-
Are you sure the radios are hw and not w only? Make sure you have the irq pin connected on gateway and nodes.
-
The HW are the high power version, w are the standard. I'm asking because I got the w delivered instead of the hw and I lost so much time because the code wasn't working since I enabled the define for the hw version

An other update:
Did a radio test:
Test program (only difference is the node id):
// *************************************************************************************** // Sample RFM69 sketch for Moteino to illustrate: // - sending // - receiving // - automatic transmission control // - button reading/interrupts // *************************************************************************************** // When you press the button on the SENDER Moteino, it will send a short message to the // RECEIVER Moteino and wait for an ACK (acknowledgement that message was received) from // the RECEIVER Moteino. If the ACK was received, the SENDER will blink the onboard LED // a few times. The RECEIVER listens to a specific token, and it alternates the onboard LED // state from HIGH to LOW or vice versa whenever this token is received. // *************************************************************************************** // Hardware setup: // *************************************************************************************** // On the sender, hook up a momentary tactile button to D3 like this: // __-__ // __| |___ // GND ----> BTN ----> D3 (D11 on MoteinoMEGA) // Load this sketch on the RECEIVER with NODEID=RECEIVER (adjust in config section below) // Load this sketch on the SENDER with NODEID=SENDER (adjust in config section below) // RFM69 library and code by Felix Rusu - felix@lowpowerlab.com // Get libraries at: https://github.com/LowPowerLab/ // Make sure you adjust the settings in the configuration section below !!! // ********************************************************************************** // Copyright Felix Rusu 2016, http://www.LowPowerLab.com/contact // ********************************************************************************** // License // ********************************************************************************** // This program is free software; you can redistribute it // and/or modify it under the terms of the GNU General // Public License as published by the Free Software // Foundation; either version 3 of the License, or // (at your option) any later version. // // This program is distributed in the hope that it will // be useful, but WITHOUT ANY WARRANTY; without even the // implied warranty of MERCHANTABILITY or FITNESS FOR A // PARTICULAR PURPOSE.

Which brings me to the question is the Raspberry pi zero w not supported? Will try the RPI3 tomorrow.
