Error in establishing a connection between nRF52840 DK board and SHT21 sensor using TWI module.

[Ashu@2000]

I  am using the SHT21 sensor for measuring temperature and humidity, trying to connect it to nRF52840 DK Board using TWI mode.

I am unable to even scan and get the response from the SHT21 sensor.

Initially, I am trying to send a basic address that is 0x80 and just confirming whether the communication is getting established between SHT21 and nRF52840 DK board or not.

I am unable to get anything on RTT viewer.

Have you used an oscilloscope or logic analyser to see what's happening on the wires
