Hi - In my app, I'm using Bluetooth, the ADC, the TWI, and the SPI. The general idea is to measure lots of things, store the data in SPI NOR FLASH, and occasionally flush some data through BLE. All is good initially, but when everything is up and running, subsequent calls to the SPI bus hang at
while (!nrf_spi_event_check(p_spi, NRF_SPI_EVENT_READY)) {}
This is with SDK 13.0 on an nRF52. What am I missing? Thanks!
