Not working on raspberry pi 3 #2

I've connected a NRF24L01 to my raspberry pi and am unable to get the examples working. I've tried both the transmit and receiver.

When trying the transmitter it never returns from the send command. Do you have the pinout that you used in your testing?

I've tried multiple configurations. Landing on this: https://www.hackster.io/wirekraken/connecting-an-nrf24l01-to-raspberry-pi-9c0a57 which I have tested with python and it does work correctly.

The examples expect the CE pin of the NRF to be connected to GPIO25, so maybe you are missing this one? (I noticed that the documentation is lacking that precision).

Did you try with the lastest master?

Nickalus commented 2 years ago

I've updated my Cargo.toml to pull from master. Still the same result with CE on GPIO25. SPI is working via spidev_test (https://github.com/torvalds/linux/blob/master/tools/spi/spidev_test.c). The result is the same though. Never returning from match device.send()

Do you compile on the raspberry or do you cross-compile on your PC? Also,the examples assume the NRF is connected to the SPI0 device, not SPI1.

I'm compiling on the Pi, and it's running on SPI0. Using the simple emitter code from the repo without any changes.

Does the scanner example work?

This was the output from that run. So it seems to be working?
