Please describe what happens when you try to repeat the read operation. Also, include the updated code so I can see what you are doing differently now.

Hello,

Please check if you are receiving the NRF_DRV_TWI_EVT_DATA_NACK or NRF_DRV_TWI_EVT_ADDRESS_NACK event instead of NRF_DRV_TWI_EVT_DONE in your callback. It's also a good idea to try get a logic trace if you have a logic analyzer or scope available. It can often be very helpful when troubleshooting i2c communication problems.

Best regards,
