I am running on the Xiao BLE normal (not sense).
I tried the new firmware updated-nosd.uf2. I can confirm Bluetooth is still working the same on my board as with the shipped bootloader, however I have had no success in sleeping, or getting the deep_sleep.ino to compile. I get the “No QSPI/SPI flash are defined on your board variant.h” error, which looking through the error further I find No such file or directory for nrf_sdm.h. In searching the example repository’s libraries, I cannot find said file.
For reference, my board is running 8.1mA with all the Bluetooth functionality working (8.6mA when I turn on the blue LED).
My hope is to run on ION_RAMON_RTC mode, which according to the datasheet section 5.2.1.1:
ION_RAMON_RTC System ON, full 256 kB RAM retention, wake on RTC is 3.16µA.
