Following these instructions you have access to the 3 hardware serials on an ESP32.
Serial0 is connected to the USB interface.
The default pins are
Serial0 - RX: GPIO3 , TX: GPIO1
Serial1 - RX: GPIO9 , TX: GPIO10
Serial2 - RX: GPIO16 , TX: GPIO17
On a TTGO Lora board the GPIO 9,10,16,17 are...
I have more than 2 Lora shields and then it is necessary to create some kind of protocol.
In the Radiohead library this funtionality is in the RHReliableDatagram.
I wish that this will be available in B4R.
If I look at the Arduino project 'rf95_client' it says:
// Defaults after init are 434.0MHz, 13dBm, Bw = 125 kHz, Cr = 4/5, Sf = 128chips/symbol, CRC on
In B4R I can change the frequency, but what are the other parameters ?
I would love the option to change these parameters from B4R :) (Please)
I have a project on my virtual drawing board that will call for the use of 2way long range communication.
Basically I will have a "master" device that will control a "Slave" by sending small packets (6 or 8 bit). The slave will then acknowledge the received message.
This is not...
