Connecting to MicroBIT

[damian burrin]

HI Guys

Great to see the IOT feature and support for the microbit.  I am having a headache getting it working.

I have downloaded the IOT Setup template and gone through the tutorial for the temp sensor and getting the following issue

Microbit successfully pairs with Samsung S5 (Android 6.01) tick appears as expected

Run the app on the phone

Scan - doesn't show the microbit

Push Microbit back into pairing mode and re-scan microbit listed in app

CLick Connect - app says connected then immediately crashes ("unfortunately app has stopped)

I've tried this on a Samsung S5 and A5 both are BLE 4 and Android 6 (stock)

Any thoughts would be appreciated.  I'd love to be albe to use this in my classes.

Thank you

Damian

Hi Damian

I've been using the BLE and micro:bit extensions for a couple of weeks now and all works fine for me.

I assume you spotted and circumvented the obvious error in the tutorial - the inclusion of an Arduino block instead of a Microbit block? 

I also assume you had a .hex file, including the Bluetooth Temperature Service, flashed to your micro:bit. Here's the one I use, done in PXT: https://makecode.microbit.org/

Hope this helps

Nope I'm still having issues.  My code is below.  When the App runs I get a C for connected but the phone app crashes immediately.  I've tried this on an S5 and A5 and get the same result.  I'm assuming it's something I'm doing wrong

Hmm - now this is interesting.  I've downloaded the examople rather than building by the template instrucitons and the error has gone and it now connects but i don't recieve any data.  I step forward and all that

Sorry to keep posting to my own reply.  I've solved this now for me.

Adding a block to force the MBit to update the temp every 500ms seems to solve the problem using the write temp period.

Not sure if its just me or this was missing in the tutorial but might be worth adding

Hi Damian

Keep up your enthusiasm! Especially if you are teaching this.

I'll try and find time to actually look at the tutorial myself - I've already reported the mistake with the Arduino block.

This new release and the micro:bit specific extensions open everything up.
