The error message means that the SPI communication failed. Sometimes it fails after h/w reset until s/w reset.
I have no oscilloscope hence not sure why it is so.

https://raw.githubusercontent.com/Wei1234c/Broccoli/master/jpgs/Broccoli_cluster_cover.gif Hi, I wrote a package with which you can dispatch tasks to an ESP32 cluster in a Celery-Canvas fashion. For an ESP32 to function as a cluster node, it needs two sets of code (in the order of uploading to ESP3...

I modified the driver, it should do the work.

It's my way to balance range and data rate, not following LoRaWAN though.

A "LoRa gateway" is an ESP32, it is also a MQTT client and a worker (like a Celery worker), so via MQTT, gatew...

FFT is so important for signal processing and many other usages, also ESP32 has ADC and DAC.

It will be very nice if FFT is built into MicroPython.

I have no SX1276 nor PyBoard, unable to answer your questions, sorry!

Hi,

I wrote a SX127x (LoRa transceiver) driver for (Micro)Python on ESP8266/ESP32/Raspberry_Pi.

ANN example is to show that an IoT network can be configured dynamically and the ANN becomes autonomous. Not very pratical, due to ESP8266's small memory .
