Re: SPI hardware

What do you see on the analyser? Do you see your data going out? Is the problem that you never get a result stored in buf? (How is buf initialised?)

Re: esp32-bluetooth.bin documentation

This is based on the WIP PR at https://github.com/micropython/micropython/pull/4589 So you might be able to figure out how to use it by reading the examples in the comments and/or looking at the code, but it's going to be tough because the PR is still being updated and I'm not sure how old that firm...

Re: bluetooth on esp32

v1.11 does not include this. By "build" I mean that you would have compiled the firmware from source (including the changes from that PR). You can also access an older version of this from http://micropython.org/download (esp32--bluetooth.bin) but you're going to have a hard time because it's differ...

Re: Trouble reading analog Input from Arduino Shield using XBee3 Module

Re: speech module on ESP32

The micro:bit port uses https://github.com/s-macke/SAM as the implementation of the speech module. I don't know what modifications they required, but you can see the implementation here: https://github.com/bbcmicrobit/micropython/tree/master/source/lib/sam SAM is relatively straightforward to use, a...

Re: Best way to log temperature from the SensorTag

Are you running MicroPython on your SensorTag (i.e. it's one of the CC3200-based ones)? 6LoWPAN is a specification for running IPv6 (i.e. internet protocol) over 802.15.4 (which is the same physical layer used by ZigBee). IPv6 is good because it's what the internet runs on, so it's easy to route out...

Re: CC3200 Texas instruments launchpad

Hi, Could you provide some more information about what you're doing? What's the sketch that you're building? I notice that you're using Windows -- from the readme https://github.com/micropython/micropython/blob/master/ports/cc3200/README.md for the CC3200 port, it looks like building is only support...

Re: bluetooth on esp32

Are you running a build from that branch?

This work hasn't been finished yet - it's still in development, and potentially might make into MicroPython v2.0

Re: bluetooth on esp32

Unfortunately there is not currently any support for Bluetooth Low Energy, but it is being actively worked on. See https://github.com/micropython/micropython/pull/4589 for more info

Re: upip micropython-os do no work properly

hi, It's really not clear without looking at the code, but the `os` module in micropython-lib is only designed for the unix port. Specifically it relies on ffi to call the libc implementations of these functions (and you have neither of these things on your ESP32). So what's going on here is that am...
