Yeay! I'm glad to hear that it worked out!

I can only speculate on why our builds are different. Maybe the compiler might have an impact. I built these with arm-none-eabi 8-2018-q4-major (aka 8.2.1).

I found the schematic for the BLE400 board: https://www.waveshare.com/w/upload/1/1b/BLE400-Schematic.pdf I have not studied in detail yet, but i suggest that we also try to swap the RX and TX. As this is not really clear to me in the schematic. Attaching the 3 hex files i have generated from today's...

Hi bogdan, I did play with the pca10028 as recent as this week. For me it did work. Could you try hit the reset button on the board a few times to see if it eventually comes up? There has also been a recurring issue with Segger and RTS/CTS. You might want to try disable Flow Control in the boards/mp...

It is a bit hard to tell what is going wrong here. Which revision of the board do you happen to have? You can also try the manual steps, just to make 100% sure you are flashing the correct files: nrfjprog --program drivers/bluetooth/s140_nrf52_6.1.1/s140_nrf52_6.1.1_softdevice.hex --sectorerase -f n...

Hi wrickert, I used the pca10056 board when developing the PR for the pca10059. You are correct, the only change needed to get it spinning is to add `#define MICROPY_HW_USB_CDC (1)` in the mpconfigboard.h to make it use USB CDC instead of regular Segger UART. Next i do the following: make BOARD=pca1...

Hi Sebi, I am talking to Glenn Rub right? Yes =) How to enable successfully the FAT file system? It's definitely possible to use FatFS on the internal flash. However, we discovered that FatFS on internal flash had substantial overhead in terms of space of partition/file table and kind of bad utiliza...

Hi Sebi, I'm using MICROPY_FATFS very often with the nrf-port together with SD cards, specially if the internal storage of microbitfs is a bit to small for for my usecase, or if i want to have a way to swap out large set of scripts without freezing them. nrf port sample on mounting hard-soldered SD ...

Assuming you are looking for an example with a Central GATT client and Peripheral GATT server, you are very close. :) If you look in ports/nrf/examples/powerup.py there is a full example of a remote control for the PowerUp3.0 acting as a Central GATT client. In case you require bonding in Central, t...

Did you also flash the SoftDevice? Else it will not be able to hit the application firmware, it needs the SoftDevice to jump to the application in case of SD=s132.

There are no pre-built images for nrf-port targets as per today. However, if you want i can create one for you. If you can just reply to me from the checklist below, i can compile one for you: * Do you want from latest master, or from 1.10 tag? * Which target board do you want it compiled for? * Wit...
