When enable Bluetooth LE REPL (MICROPY_PY_BLE_NUS (1)), get the following errors:

Possibility to have Bluetooth and USB CDC REPL working simultaneously ?

My board has no ext. 32 kHz crystal and needs the following: CFLAGS += -DBLUETOOTH_LFCLK_RC to work properly, should this be an option in mpconfigboard.h ?

Micropython support for the SPIM — Serial peripheral interface master with EasyDMA ? Also, looked at the micropython examples, but was not able to find examples for controlling the peripherals in C/C++ - Pins, PWM, Timers … Any available ?

In, micropython/ports/nrf/modules/machine/adc.c in nrfx_saadc_simple_mode_set instead of NRF_SAADC_INPUT_DISABLED isn't supposed to be SAADC_OVERSAMPLE_OVERSAMPLE_Bypass ?
