Hi,

What would you like to ask?

Hi,

I'm not sure if this is an appropriate question for this forum.

I'm desperate to be able to communicate with a 'Bluetooth Bracelet', in particular the 'Wireless Buzzband BT-88' or the 'Xiaomi Mi Band' using the HM-10 bluetooth module (via an Arduino)

I'm sure this must be possible, if so, can anyone help with coding advice?

Many thanks,
Paul

There is nothing hard. The Bt-88 is BLE device so check which services it supports. Then refer to services docs and set required characteristic value to vibrate it.

Hi,

If only it was that easy! I have tried to find out all I can, with any luck, hence joining a forum.

Hi,

Well. This forum is for WCL support but if you would like you can e-mail me to mike@btframework.com (or to btframework@gmail.com) with your problem details and I will try to help.

Hi,

Many thanks - what would be very helpful is knowing:

1. what the default frequency of the Bracelet are
2. what to send in regards to telling the device to buzz, so, do I send the word "buzz" or "BUZZ" or "VIBRATE" ...so on
3. do I need to know the devices MAC_ADDRESS? If so, how do I find this out?
4. can I assume the sent commands (to the Bracelet) are all AT Commands?

1. what the default frequency of the Bracelet are

Can be found in bracelete docs.

2. what to send in regards to telling the device to buzz, so, do I send the word "buzz" or "BUZZ" or "VIBRATE" ...so on

As it is BLE device you must write characteristic value, not sending any words.

3. do I need to know the devices MAC_ADDRESS? If so, how do I find this out?

Yes of course. In common way you have to send HCI INQUIRY command. For AT command based BT module refer to its docs.

4. can I assume the sent commands (to the Bracelet) are all AT Commands?

No. It is binary GATT protocol.
