https://devzone.nordicsemi.com/f/nordic-q-a/78092/i2c-busIn my project, nrf9160 has to send and receive data from the I2C bus from a chip. Everything works fine but unfortunately I have to query the chip by sending a single byte (address only) while the chip is working. If I send 2 bytes, for example the addressen-USTelligent Community 13Wed, 11 Aug 2021 14:29:58 GMThttps://devzone.nordicsemi.com/thread/324524?ContentTypeID=1Wed, 11 Aug 2021 14:29:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e1530f0b-af7c-4cd1-92db-ed35160204fehelsing<p>Hi massimo,</p> <p>Our hardware does not support sending only the address.

My problem is not on the I2C because it works fine until I send the address + the data ... The problem arises when I have to send only a single byte (the address) with no other data. How can I achieve this?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/322884?ContentTypeID=1Mon, 02 Aug 2021 12:58:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:be39c54e-54bf-488d-b33e-992749ad19c8helsing<p>Hi massimo,</p> <p>Thank you for the request. Could you please provide some more context, like how does your system crash and which chip you are communicating with? Would you be able to share your overlay file?</p> <p>Do you have access to a logic analyzer, or do you have any recordings from a scope available?</p> <p>Best Regards,</p> <p>Håkon</p><div style="clear:both;"></div>
