    OSI Layer 2 driver for nRF24L01 on Arduino & Raspberry Pi/Linux Devices

    Project mention: RF24 ack payload | reddit.com/r/arduino | 2021-09-18

    I'm trying to get acknowledgement payloads to work with an esp32 as the sender and an uno as the receiver.

The example code works as intended but stops working when I try to modify the structs that contain the data, and I don't know why. How can I make my own code work?
