Hooray! I have finally found the error! :)
The problem is struct byte alignment is different on arduino and on teensy3. Consider structure
typedef struct{ //5 bytes
unsigned long timestamp; //4 bytes
uint8_t crc; //1 byte
} snapshot_t;
Since teensy is 32bit...
Code written for communication using nrf24l01+ works if I use two arduino UNOs.
But when I try to upload the same code for receiver to teensy3.1 using the same nrf24l01+ board, it does not work.
All I can see on serial monitor is "tick". No data is received.
"Sender" runs on Arduino UNO.
SPI...
