RE: Using pc-ble-driver-py on Raspberry Pi

XavierYin — Sat, 04 Aug 2018 03:31:02 GMT

Key points to run examples on RPI (w/ DK):

1. no need JLink software
--- DK flashing ---
2. flash nRF on DK by PC, I just tried the 115200 version
--- pc-ble-driver-py ---
3. compile boost from source, version <= 1.65.1
4. install pc-ble-driver-py from source
--- HW part ---
5. cut solder bridges on DK to isolate nRF UART pins from interface MCU
6. wire connect nRF UART to RPI GPIOs
--- RPI part ---
7. enable RPI UART w/ HWFC
--- Python part ---
8. turn off auto flashing if you with to try examples
9. make sure UART setting matches connectivity FW that was already flashed in step 2
10. run examples by explicitly assign UART that is enabled in previous step

to flash / erase afterward :

1. cut solder bridges on DK to isolate SWD pins from interface MCU
2. wire connect nRF SWD pins (TPs on DK) to RPI GPIO
3. bitbang SWD on RPI & do your job with it

Hope this helps

Xavier, can you elaborate on your solution? I am at the same point as you were getting the Error Code 13. How did you connect nRF directly to the Pi?

Thanks for those links, but unfortunately they doesn't help much.

The problem is actually about the interface MCU. We circumvented by connecting nRF directly to Raspberry Pi and it works as expected. It's not a piece of good news for people who simply wants to quickly test serialization with DK and Raspberry Pi, but for my case the problem was solved.

Hi Xavier,

Please check out this thread, it looks like it could be the same issue.
