I would suggest you look into either the one that you already are, or the twi_master_using_nrf_twi_manager.

Hello,

The TWIM pins in this example are set in a file called config.h, but only the pin numbers, not the pull configuration.

If this example is not modified, the pull configuration is set in nrfx_twi.c -> nrfx_twi_init() -> TWI_PIN_INIT() -> where it is hardcoded to pullup.

Just FYI: In the unmodified twi_master_with_twis_slave example, the twis' pull is set in eeprom_simulator.c -> eeprom_simulator_init(), not in sdk_config.h.

BR,
Edvin
