Need support with Grove - BLE (dual model) v1.0

Products & Technology Grove
#1

Hello,

I need to send data between win 10 desktop and your dongle connected to a microcontroller. So far about nothing is working, so I need some technical support!

  1.   You provided some API at http://wiki.seeedstudio.com/Grove-BLE-dual_model-v1.0/#tech-support  so one can setup the dongle.

But some commands are not working, or I enter them in incorrect way. Here is an example when dongle is just connected, so no previous commands.

  1.   In order to use it from windows side, I have to use Bluetooth LE Advertisements. https://docs.microsoft.com/en-us/windows/uwp/devices-sensors/ble-beacon

How to setup them in your dongle? Does it support it? Is it automated?

Best Regards,

Michael

Hi

Michael,


1. For the AT command, we use the HM-13 module and You can refer to the AT command(
  1. AT Commands

)in https://raw.githubusercontent.com/SeeedDocument/Grove-BLE-dual_model-v1.0/master/res/Bluetooth_HM-13_en.pdf


2. For the API, we have arduino example as below. It uses the software serial(D2/D3 pin of arduino board)

3. For

Bluetooth LE Advertisements, Sorry, we do not have the experience on this, thanks for understanding.

I found out the mistake – it was bad Bluetooth drivers on my PC.

Hello its me again

I have problems with dongle. I need to set up the baud rate to 19200 and 2 stopbits. So I connected on 9600 8N1, wrote AT+BAUD3, it answered OK+SET:3 and now I can not connect to module at all. No combination of baud, stop bits, power on/off works. Here is the picture – I don’t have reset button. Please provide help.

Hi there,

Sorry for the late response. I config the baud rate as 19200 through AT+BAUD3, and i can communicate with PC well. Here is the software i used. If you change the baud rate, it does not work, you have better to power off and power on again the module.

I did the same using your software. Dongle worked on 57600, I set baud to 19200 using AT+BAUD3 and now I cannot connect to it at any baud. No idea how to reset it. Power on/off does not help. I think we have bad (fake?) dongle…
