As of today (2019-10-10), it is now possible to activate MICROPY_PY_SYS_STDFILES in mpconfigport.h for the nRF port: see this issue on GitHub and the corresponding commit by @dpgeorge to fix it. Additionally, MICROPY_PY_MATH_SPECIAL_FUNCTIONS can also be enabled following the recipe presented in the...

Dear c45713, I am talking to Glenn Rub right? I was thinking of activating the FAT file system on the main flash memory of a nRF52382 board (it is a fitness tracker wristband and there is no possibility to connect an external SD card to it). As I wrote in this issue on GitHub activating the FAT FS r...

Dear community, I encountered some issues with the nRF port on a nRF52382 board and would like to submit them to you: - I was unable to turn on some of the features in mpconfigport.h , such as MICROPY_PY_SYS_STDFILES , MICROPY_PY_MATH_SPECIAL_FUNCTIONS , MICROPY_PY_IO_FILEIO and MICROPY_PY_MACHINE_S...

Here are the errors obtained after invoking rshell (and pyboard.py): - with MICROPY_FATFS enabled: (MPY) C:\MicroPython\CODE\>rshell -p COM1 Using buffer-size of 32 Connecting to COM1 (buffer-size 32)... Trying to connect to REPL connected Testing if ubinascii.unhexlify exists ... Traceback (most re...

I cleaned up the board definition and attest it gets pretty standard when compared to others': dsd6.zip Unfortunately I don't have any other nRF board to test if I encounter the same issues copying files using pyboard.py or rshell. Currently the only solution I have found to copy files onto my board...

Which specific board and nrf52? Thanks Jim for trying to solve my issue. The board is indeed not standard: it is a MPOW/Desay DS-D6 fitness tracker with a nRF52832 ( https://forum.micropython.org/viewtopic.php?f=12&t=6498#p36981 ). Enclosed are the board definition files: mpconfigboard.zip It is th...

Dear community, I am having difficulties copying files onto a nRF52 (using standard tools such as pyboard.py, rshell, ...) I have never experience such issues with other ports (esp8266, esp32, ...). Does a special feature needs to be set in the build to successfully copy files? Error illustration: C...

Can you describe a bit more what buffered stdio is used for? I am having difficulties copying files (e.g. using pyboard.py) onto a nRF board, and I assume this is due to not having the buffered stdio enabled in my current build. Do you confirm this could be a reason? I have applied the content of yo...

I figured out how to use OpenOCD to program the nRF52840-dongle using only a Raspberry Pi as the debugging interface (no need for a J-link). I made a YouTube tutorial if anyone is interested: https://youtu.be/R5wub5ywzTU Nice video! (I also use OpenOCD but with a ST Link-V2.) nrfutil pkg generate -...

I just created a NUS Telnet gateway based on the original nus_gateway design in nodejs using noble.

Interesting! Can you share that work with us?
