please add this feature
I'm sorry :) I solved the issue. beeing root is important :) so instead of `nrfutil dfu serial -pkg D6-DS.zip -p /dev/ttyUSB0` I had to use `sudo nrfutil dfu serial...

I just measured it with my multimeter, the RX/TX pins are always at about 3,5V when high. Probably 3,5V is enough to be a logical 1 in most 5V setups....
how far are the kx022 and kx023 identical?
because here is a c library for the kx022 that might be quite easy to port https://github.com/goran-mahovlic/nRF51_ID107_libs/tree/master/libraries/KX022
Thank you very much :) And do you have something similar for the HR sensor (illuminating the LED and reading back the brightness value)?
I found a datasheet: https://pdf-datasheet-datasheet.netdna-ssl.com/pdf-down/P/A/H/PAH8001EI-2G-PixArt.pdf I'm highly impressed with the complexity of what I believed to be a phototransistor and a led 😅
unfortunately the datasheet doesn't seem to be complete, I found some C code for the sensor on github that writes to 0x27-0x29 and those are not named in the datasheet....
here is some very basic code to simply read something from the hr sensor (simply the first 8 bytes (8 is an arbitrary value) in this exmaple); its written in...
