RFM95W LoRa Bonnet ID #4074 Autostart Problems

Post by rkmason »

Hi, I have just started testing radio communication between 2x of Adafruit item #4074 LoRa Bonnets attached to RPi Zero W units. My question is about autostarting the "radio_rfm9x.py" test program. I have followed the Adafruit basic setup and testing tutorial for these LoRa radios and I have them communicating successfully when I manually start the python programs after bootup of the RPi Zero W's. I want this python test program to autostart on RPi Zero bootup so I can begin range testing using the RPi's standalone without a serial monitor. When autostarting the python test program from the /etc/profile file, it appears that most of the time the LoRa radio does not get configured correctly so the radio will not communicate and the test fails. My assumption (just a guess) is that there needs to be some program startup delay added for the radio to reliably configure. I'm not sure where to look at this point.

Any constructive feedback on this topic appreciated, Thx
