bluetooth setup?

Post by sanandak » Thu Nov 07, 2019 4:18 pm

I flashed
PYBD-SF2-20191106-v1.11-563-g4be316fb0.dfu
to a pyboard D (SF2)

import bluetooth
and
bt = bluetooth.BLE()

both work without error
but
bt.active(1)
simply hangs. The REPL never returns. I have to interrupt with ctrl-C

bt.active() returns False.

Any suggestions on how to trouble shoot? Or a different working micropython image?

Thanks,
Sridhar

Could you please show us the output of flashing the Pyboard? (e.g. the output of dfu-util). Thanks

Hi, here is the output of flashing the pyboard (using pydfu.py)

Hi,

Thanks for that.

I'm going to send you a firmware build with some extra debugging, but in the meantime, can you do a simple test just to rule out some other things.

- Install urequests.py (copy the file directly from https://github.com/micropython/micropyt ... equests.py )

- Connect to WiFi

- Run this at the REPL:

Code: Select all

>>> import urequests
>>> urequests.get('https://micropython.org/ks/test.html').text
(Basically just need to know that both wifi and SSL is working)

Thanks!

Could you please try flashing this firmware and trying the following things:

https://drive.google.com/file/d/16nVtXe ... sp=sharing

Code: Select all

>>> import bluetooth
>>> ble = bluetooth.BLE()
>>> ble.active(True)
This should print out a reasonable amount. If you can paste it into a https://gist.github.com/ (or equivalent) that would be great.

Next can you please verify that the flash data is being read back from the external qspiflash correctly (either copy this into a file and import it, or use Ctrl-E to enter raw repl, paste, then Ctrl-D to run). Again, please post this to a gist or similar.

Code: Select all

import uctypes
import uhashlib

addr = 0x90000000
addr_end = addr + 0x200000
n = 0x10000
while addr < addr_end:
    h = uhashlib.sha256()
    h.update(uctypes.bytearray_at(addr, n))
    print(h.digest())
    addr += n
    
Thanks again!

jimmo - thanks! but still have trouble:

output of bluetooth active() command:
https://gist.github.com/sanandak/17d4eb ... 52e853d778

it still doesn't return to the repl after the debug messages...

contents of the flash:

jimmo - I built a dfu from the latest version on github and that seemed to work!
Thanks for all your time and effort - much appreciated!

OK, glad it's working, but please let me know if you see the issue again.

If you did have a minute to investigate further, I'm curious as to why building from latest master was any different...

Is it possible you were using an older version of pydfu.py (like before mid last year), and then when you built from source you also updated your repo to the latest version?

Do you see the same issue if you use dfu-util on the pre-built firmware images?

Hmm.. that might have been it. (though the pydfu was from earlier this year- I only purchased the pybd this summer...)

I re-flashed the image downloaded from micropython.org (the one that gave me trouble):
MicroPython v1.11-563-g4be316fb0 on 2019-11-06; PYBD-SF2W with STM32F722IEK

and this time bluetooth worked fine.

Thanks for your time - I have some paths for troubleshooting in the future!
Sincerely,
Sridhar
