High Sleep Current (450ua) on NRF52 after starting SPI

10 Nov 2018


Having issue with high sleep current after starting SPI channel. If i start the SPI, read a sensor and then sleep using Thread::wait, i get unusually high sleep current, as if the high speed clock is still running.

Why is this, do i need to shut down the SPI first, and if so how do i do this as the SPI class has no function for this?

Same is also true with I2C.
