[Question]: Are nRF24 chips capable of tx/rx in higher freq. ranges? #1056

What would you like to know?

An interesting post was made a couple days ago on the Arduino Forums.

https://forum.arduino.cc/t/maximum-channel-frequency-nrf24l01-aboveghz/1425990/9

A user is suggesting that (some or all ?) nRF24 chips will function up to around channel 180 instead of just the range specified by the manufacturer. (0-125)

Since RF24 lib technically limits the max channel, I have been considering removing the limit.

I don't have any way to test this out, so thought I would make a post about it, in hopes somebody can confirm. Of course I can set a higher channel and test, but that doesn't confirm the radios are actually operating in a higher range. We need somebody with a High freq SDR or something to verify.

Change:

void RF24::setChannel(uint8_t channel)
{
    const uint8_t max_channel = 125;
    write_register(RF_CH, rf24_min(channel, max_channel));
}

to

void RF24::setChannel(uint8_t channel)
{
    write_register(RF_CH, channel);
