  1. Teensy 3.6 with nRF24L01 Tx buffer data queue

    Hello. I am trying to send 256 bytes of known data each cycle (numbers) between two Teensy 3.6 through nRF24L01 radios. Using radio.writeFast we can send up to 32 bytes at a time. Basically, we would...

    I think the issue was that we were trying to declare a variable too big inside the update function, so the program was crashing. It seems to be working now. Thanks!

    Well, doing this test you suggested, it seems the nRF module is working fine.

    CS: High -> MISO: 1.65v
    CS: Low -> MISO: 0.1v

    Yes, 2 10k resistors in a voltage divider. Do you know any basic SPI code we can test with the nRF20L01 so we can make sure it is a software issue and not a hardware one?

    Doing the 2-resistor MISO test, the results we got were these:

    When CS is LOW (active), MISO was 1.5V
    When CS is HIGH (disconnected from nRF module), MISO was 1.65V

    These results seem to be...

    I have tried with 40 ohms since I don't have 47 ones, I guess there would be minimal change in current if I use 40 instead of 47 ohm
