3 years ago Hello,
following some examples in https://learn.adafruit.com/radio-featherwing/using-the-rfm69-radio I could establish some SPI communication between the HUZZAH32 and the RFM69 Radio. So at least my hardware and cabling seem fine.
@FiorixF1 : when pulling your RadioLib again today I noticed you made some progress : [RF69] Fixed setOOK() however this results in some compilation error. maybe:
int16_t state = SPIsetRegValue(RF69_REG_DATA_MODUL, RF69_OOK, 4, 3);
should read:
int16_t state = _mod->SPIsetRegValue(RF69_REG_DATA_MODUL, RF69_OOK, 4, 3);
with the two lines modified compilation is fine, but not sure if it's what you intend, there is also a function with the same name defined in Module.h/cpp.
P.S. nice to see there is some progress ;-)

Hello,
to start with I ordered and assembled the same Adafruit modules found on the photos on the RFQuack github site:
Since there is not much one may do wrong there I thought it should be straightforward to get at least some communication between the HUZZAH32 ESP and the RFM69HCW CC1101 Radio Feather (I used the same wiring for the for the CC1101 CS, IRQ and RST as one may find on the github photos).
However there is no communication on my modules (I programmed the HUZZAH32 with some other examples using Arduino IDE and Espressif-IDE and the module seems fine).
From the photos and the schematics, I used Radio CS=13, IRQ=27 i.e. Radio = new Module(13, 27, RADIOLIB_NC). By chance, since this is exactly the same setup: can anybody confirm these?
To me this seems quite strange: these Adafruit Feathers use GPIO 18=MOSI, 19=MISO, 5=SCK whereas the ESP32 VSPI is on GPIO 23=MOSI, 19=MISO, 18=SCLK. Of course one may use whatever IO ports and implement a SPI bus, but it would be better to use the one provided by the hardware chip. Anyway this seems just a detail and probably not the cause for my problem.
cheers, Dirk
