Ham radio protocols and Arduino examples for LoRa on 70cm.
Couple of thoughts I had while converting the pager.ino for use with a ESP32 board 1) Tokenize (sp) the sending string - making it easier to manipulate on the rx...
The SX1276 datasheet warns that max duty cycle at +20dBm is 1% - suggest running max of +17dBm from the chip itself. I also note that the radiohead library seems...
In its current form, `loraham` uses the default modulation settings defined by the Radiohead driver. This configuration may suboptimal given the project's implicit goals of long range ad hoc networking....
* Adds a new configuration for the modem: SF=12, Cr=4/7, Bw=125kHz, CRC on, Low data rate optimization on * Spreading factor 12, 4096 chips/symbol, is the slowest but gets us...
When a solar charged device runs low on power, it dies. That much is unavoidable, but when the sun comes back and the LiPo recharges, the node stays dead, either...
This will allow the PocketCHIP to boot when connected
Resolved when compiling `gateway` for 32u4 (in addition to m0) is as easy as uncommenting or commenting a few `#define`s
It seems when you define the RTC into the new gateway code, that you loose the USB port as a usb->serial. And the reason is because in the sleepsetup() call...
What range are you getting between your transmitters and receivers with omnidirectional antennas?
