NRF52840 Proprietary 2 Mbps.

[Ted]

Hi friend,

I used SDK16.0 and softdevice is S140.  I want to use nRF52840 proprietary 2Mbps mode. Do you have example code to provide me?

Thank you in advance.

Hi Simon,

We want to generate 1 kHz OOK symbol rate, Manchester encoded (For a 0.5kHz bitrate) and 40-bit pattern – start with this one for now: [0xAA, 0xFE, 0xCA, 0xBB, 0xED].

Can make it by nRF52840 platform?

Thank you very much.

Hi Ted

The radio peripheral on the nRF52840 is a 2.4GHz transceiver, and can not output 1kHz if that's what you're asking. I guess you could do something with the PWM peripheral to generate the Manchester encoding data you'd like, and transmit that over the air using the radio. Unfortunately we don't have specific example projects doing exactly that, but in addition to the radio transmitter example, you could also check out the PWM driver example project.

Best regards,

Simon

Hi Simon,

The last question I did not describe is very clear. I need is a 1KHZ OOK signal modulated on a 2.4GHZ carrier. The 2.4GHz carrier is on if data is high, the 2.4GHz carrier is off if the data is low. It is OOK modulation instead of GFSK. Can NRF52840 achieve it? I will send 40-bit pattern 40-bit pattern [0xAA, 0xFE, 0xCA, 0xBB, 0xED].

Best wishes

Hi

We only support the modes that are described in the PS. The radio does not have support for OOK modulation I'm afraid.

Best regards,

Simon
