some modifications for python 2.7.16

[ilievinti]

• Wired like: https://circuitdigest.com/microcontroller-projects/wireless-rf-communication-between-arduino-and-raspberry-pi-using-nrf24l01

• I used script: https://github.com/BLavery/lib_nrf24/blob/master/example-nrf24-recv-rpi.py ... thank you Brian Lavery 👍

• radio2.begin(0, 25) csn=0 means pin nrf24-csn to rpi-gpio8 (CE0_N) and pin nrf24-ce to rpi-gpio25

• while True: .... akpl_buf = [(c& 255), ... (like in another example)

• I change library https://github.com/BLavery/lib_nrf24/blob/master/lib_nrf24.py :

• after lines self.spidev.open(0, csn_pin) self.ce_pin = ce_pin i add line:

• self.spidev.max_speed_hz=(4000000); because: https://github.com/nRF24/RF24/issues/205#issuecomment-180104230

• and to line 226 i use line "if isinstance(value, (int, long)):" (not: "if isinstance(value, int)")

• ---

Commands on raspberry pi zero (virgin sd card with Raspberry Pi OS Lite):

• sudo raspi-config ... to config. wifi (ssid and password)

• sudo apt update

• sudo apt full-upgrade

• sudo apt install git

• sudo git clone https://github.com/BLavery/lib_nrf24

• cd lib_nrf24

• sudo nano example-nrf24-recv-rpi.py ....... see modification

• sudo nano lib_nrf24.py ...... see modification

• sudo apt-get install python-pip

• sudo pip install spidev

• sudo python example-nrf24-recv-rpi.py

THANK YOU @ilievinti ! I've searched the ENTIRE Internet. Browsed every page of Internet archive. TWICE! But with no success. ;) Next time I know what to do - find the repo, and look under issues.

I've had a script running on different RPi's for years based on this code. Literary years ... so when I finally thought Raspbian Jessie was a bit old and did a fresh install of Buster - my script stopped working.

In desperation I installed the latest Raspbian Stretch (which now is old but not as old as Jessie), and the script started working again. That told me it wasn't a hardware issue ...

On Buster - as soon as I did radio.begin(x,x) it crashed. And the solution was nowhere to find - but here.
