Cannot connect to ATECC508A through TWI with NRF52832. Tested with nRF5_SDK_12 twi_master and deprecated twi_sw_master. It was working fine only with NRF51822 nRF5_SDK_12 using deprecated twi_sw_master.

Have you checked that you have connected the correct pins defined in your code? Do you get any error codes? Have you checked the bus using a logic analyzer, to see if there are any activity?
Hi,
I also have this problem, when connect to ATECC508A and send a simple info command, but I always got
NRF_DRV_TWI_EVT_ADDRESS_NACK and NRF_DRV_TWI_EVT_DATA_NACK and never get it done.
I re-send the info command when receiving NRF_DRV_TWI_EVT_ADDRESS_NACK or NRF_DRV_TWI_EVT_DATA_NACK but situation is the same.
Any idea what's wrong?
thanks..
