9160/52811 communication

[Tron]

Hi 

We will use the 52811 together with nRF9160 for short range communications. Currentconsumptionwise which interface is recommended, UARTR, TWI or SPI?

Hi!

With current consumption as the only factor, I would recommend SPI(M), as you are able to move more data within a shorter amount of time, resulting in the lowest current consumption on average.

However, note that the average current consumption for the different interfaces also varies depending on how they are used.

Best regards,

Heidi
