SENT protocol based sensor configuration with nrf boards

[AkbarShah]

hey there, i have a project which uses  nrf9151 with a pressures sensor from BOSCH which uses SENT protocol to transfer data, my question is

1. Is it possible to configure the SENT protocol on the nrf9151
2. if yes, how am i gonna configure what should i use?

Hello,

We don't have any SENT peripheral on the nRF91 series (or any of the other device that we have). 

I have not heard about it before, but is it a 1 wire protocol, where they just have a longer pulse for higher value? Or how does it work?

And how is the flow? Do you need to request the data? Or will it continuously send data using the SENT protocol? How about the voltage level of the signal? What does it look like?

Best regards,

Edvin

Hi,

SENT protocol is (SINGLE EDGE NIBBLE TRANSFER) which transfer data encoded in the falling to falling edge period of the signal, it works according to the (SAE J2716 JAN 2010 standard).

And how is the flow? Do you need to request the data? Or will it continuously send data using the SENT protocol? How about the voltage level of the signal? What does it look like?


No ,it continuously send data we don't need to request it. the voltage level is it operates on 5v.

i have tried the approach this dude shared but i am unable to get any capture period, also i can not use ADC as its an digital signal.
