### 2025-02-28
Started all over again. This time I succeeded! The Waveshare ESP32 S3 Pico and the Ra-02 SX1278 LoRa transceiver are working as a proper rnode. It took me some time, but now I am happy. See Documentation/HOWTO-change-firmware-and-compile-it_MeesElectronics.md for more information about adding a new board to the code.
Pinout Ra-01:
|pin|GPIO|
|---|----|
|NSS|39|
|MOSI|37|
|MISO|36|
|SCK|38|
|RST|40|
|DIO|35|
But pinout can easily be mapped to other pins.

In **Utilities.h** the functions **led_indicate_info()**, **led_indicate_standby()** and **led_indicate_not_ready()** is also defined for the different boards. If the new board has a NeoPixel, nothing has to be added her.
In **Utilities.h** the function **bool eeprom_model_valid()** also has some board specific definitions. Make sure these are set correctly to prevent an EEPROM error during startup:
In **Utilities.h** the function **void setTXPower()** defines the LoRa power setting per Lora module/board pair. Add the new board here:
// Added by Mees Electronics
if (model == MODEL_A4) radio->setTxPower(txp, PA_OUTPUT_PA_BOOST_PIN);
The file **display.h** also has a board definition section. If the new board has a display, make sure there is a proper entry for it. Again, inside the '#if MCU_VARIANT == MCU_ESP32'. If the board does not have a display, don't define this section.
The file **Power.h** must also have a board definition. And also proper definitions in **void measure_battery()** and **bool init_pmu()**. These are more elaborate and not yet fully understood, but probably used when the board has a battery installed. If the new board does not have a battery, do not define anything here!
Sometimes the board give error whule flashing. Try flashing the board via the other serial interface (ttyACM1). Don't know why, but it works.
### Migrating to a other system
When the rnode is flashed, it is signed with a key. If you connect the rnode to another system, this key cannot be validated. It is possible to write a new key to the rnode by erasing the eeprom and writing the local key to it.

I checked the SPI communication with an oscilloscope and that all seemed to be working. I could find the problem. Than I remembered the second serial interface on the Waveshare board. This interface was available on the USB port via the onboard USB hub. Maybe the rnode spits out some sort of debug information. So I installed *screen* on my pc and started it:
$ screen /dev/ttyACM1 115200

An RNode is an open, free and unrestricted digital radio transceiver. It enables anyone to send and receive any kind of data over both short and very long distances. RNodes can be used with many different kinds of programs and systems, but they are especially well suited for use with [Reticulum](https://reticulum.network).
