BLE radio blocking the CPU for too long
On the nRF51822 with an active BLE radio, the CPU can be blocked any time for as long as 1.5 ms. This makes other communication channels lacking flow control (eg. SPI in slave mode) very low throughput. See my case here: https://devzone.nordicsemi.com/question/105249/spi-slave-and-ble-on-nrf51822
Is it possible to cut down on this time?
