I have extensive experience in the medical device industry, and am confident that Micropython is suitable for medical device development. In the US, the FDA cares about safety and efficacy and regulates interstate commerce. If you can demonstrate your device is safe and you have the appropriate cont...

I made a build as suggested by jimmo with debug flag enabled, and modified the ble_temperature to send data more quickly to a second pyboard-DSF6 running ble_central.py example. See https://forum.micropython.org/viewtopic.php?f=20&t=8844 for more info on the test setup. nimble: characteristic_access...

As a workaround you can use the .flatten().tobytes() methods. a = np.zeros((1,1)) b = a.flatten().tobytes() This won't give you an error, however it doesn't function properly. I think there may be a bug in the .tobytes() file as the lenght of the array is off by a factor of 8 (the size of float obje...

Additionally, I notice that it is not possible to configure that rxbuf parameter associated with the ble. >>> MPY: sync filesystems MPY: soft reboot MicroPython v1.13-268-gf7aafc062 on 2021-01-11; PYBD-SF6W with STM32F767IIK Type "help()" for more information. >>> import ubluetooth >>> ble = ublueto...

Thanks for the reply. That certainly makes sense. Another oddity I see is when running this code: import pyb import utime dum1 = utime.ticks_us() dum2 = 0 dum3 = 0 dum4 = 300 dum5 = 0 a = 0.5 def tick_motor(timer): global dum1,dum2,dum3,dum4,dum4 dum2 = utime.ticks_us() print(dum2-dum1) while dum3<d...

I have a question regarding the difference in utime.sleep_ms() compared to utime.sleep_us(). I am using a Pyboard D-Series SF6 with Micropython V 1.13. First off, I know that I should not generally be calling utime.sleep inside of a timer callback. I am doing this as a unit test as part of a larger ...

I have a similar issue where I am trying to log sensor acquired data quickly, and tried the solution proposed above: import uasyncio as asyncio async def sender(): with open('test.txt', 'w') as f: swriter = asyncio.StreamWriter(f, {}) while True: await swriter.awrite('Hello file\n') await asyncio.sl...

I have been working with the ble_temperature and ble_temperature_central examples (https://github.com/micropython/micropython/tree/master/examples/bluetooth). I have 2 PYBD-SF6W running MicroPython v1.12-652-gcaaaa2b1f , running a file on each one of them. I am running the ble_temperature_central.py...

I recopied your demo files and added the code you suggested and I saw the same output as you. After reviewing, I noticed that I had changed the sleep_ms to sleep_us in the ble_temperature.py file when I first started working on the example to try and stress the ble link. It was throwing a memory err...

Yes, that is the setup that I am working with. I am able to read fine, but when I put in a print statement to debug the events that are called in the _irq function, I never see 8192. def _irq(self, event, data): print(event) if event == _IRQ_SCAN_RESULT: addr_type, addr, connectable, rssi, adv_data ...
