Open dewi-ny-je opened 5 years ago
I'm not familiar with RFM69 enough to judge what changes to the protocol would be needed - if any. If there's a RFM12 compatible mode in RFM69, it should be possible to implement the support.
Currently the biggest problem of this project is timing and memory - interrupt based communication with RFM would be beneficial to current polling methods - polling works but places big constraints on the rest of the code (namely WiFi communication).
Honestly I need to get back to the project and finish it to at least reliably working state as is. Base communication works well, but the stability leaves something to desire.
RFM12 modules are getting more difficult to find.
Basing this project on a RFM69 module used in RFM12-compatible mode would be preferred.
Porting the whole OpenHR20 to RFM69 to reduce power consumption and increase range would be even better, but it involves a lot more work and it's beyond the scope of this project.
