NRF24L01 connection with ARM microcontrollers

cucumber God 10 May 2020, 11:35 last edited by

can I use [48MHz microcontroller(STM32F0xx)+NRF module] at Transmitter side and [72MHzmicocontroller(STM32F1xx) + NRF module] at Receiver side?

I have published all the documentation in a Github repository. If someone wants to make PCBs, I recommend that you wait a little longer until you receive my PCBs and try them. https://github.com/giltesa/SmartHome

@terxw okey, thanks for reporting back !! Let me know if there is something else. This is a 0.5v so I'm open for improvements.

@xefil said: Thanks @hek and @kalle Sorry, but I'm not good to understand the debug of the scanners. In the RF24/examples/scanner/ the range is between 0000->->->7777 Those are the high order nibble of the channel byte. The low order nibble is just below it. The 125 channel numbers are printed "sideways" in hex. I would expect a list of channels between 1 and 13. You're thinking of wi-fi. This isn't wi-fi. In the second scanner (wiFi scanner found on arduino forum) It's more accurate. It seems noisy between channel 3 and 9. So, the questions are: What does default channel 76 mean? 2476Mhz? yes Would mean above channel 13, on channel 14. In this case these channels are free, based on the results. I've seen I can use: #define RF24_CHANNEL 76 //RF channel for the sensor net, 0-127 How to interpret the scanners result? Most of all the "RF24/examples/scanner/" which has an output I cannot identify in a channel. The bigger the number below the channel, the more active it is. I would like to understand the result and so choose the right channel, not only trying without knowing what I'm doing Thanks a lot for the support! Simon

Never mind I updated to 1.4 and tweaked the code all is working fine.
