SPBTLE-1S - How to get a BLE connection?

Hi,

I just got the EVAL-IDB007V1M with the spbtle-1s (based on bluenrg-1 and installed the STSW-BLUENRG1-DK (v2.5.0) on my Windows PC. The BlueNRG-1 Navigator recognizes the EVAL-IDB007V1M and I can 'Flash & Run' the basic examples and the BLE demonstration and test applications.

They seem to run on the EVAL-IDB007V1M - at least they to something when I press the buttons but I get strange results.

First, when I 'Flash & Run' the BlueNRG-1 Hello World from the basic examples I get this output:

With another terminal program it looks like this:

I expected Hello World... What's wrong?

Second problem (and more severe in my case): When I flash and run the BLE demonstration and test applications I would expect to be able to establish a connection to the EVAL-IDB007V1M from my Android smartphone. I tried to use the Apps STM32 BLE Profiles, BlueNRG and (sorry for that) nRF Connect. But I couldn't get any connection to the  EVAL-IDB007V1M. I tried several demo applications, e.g. BLE Beacon.

The Apps and the BLE stuff on my smartphone works in general and I can connect to other BLE devices.

Again: What's wrong?

TIA

Wolfgang

Hi Wolfgang,

please keep into account that STSW-BLUENRG1-DK  provides you with different applications. They define different proprietary profiles and require their specific counterpart app on the phone/tablet.

In order to test the BLE functionality, I suggest to run the BLE_SensorDemo application on your EVAL-IDB007V1M. In this case, you will need to use the BlueNRG app on your Android phone.

If you want to build and flash the BLE_SensorDemo project, the relative path within your SW package is:

Project\BLE_Examples\BLE_SensorDemo

If you want to use a pre-built binary, instead, you can find it here:

Firmware\BLE_Examples\BlueNRG-1\BLE_SensorDemo

Your current configuration for the terminal program (115200, 8N1, no flow control) is OK.

Best regards,

Antonio

Hi Antonio,

thank you for your fast answer. I already used 'Flash & Run' in 'BlueNRG-1 Navigator' to flash the BLE_SensorDemo. The LED DL1 is flickering a little bit but I got no BLE Connection with my smartphone (Samsung Galaxy S7) and with three different apps from different suppliers: BlueNRG, nRF Connect and BLE Scanner.To make sure BLE on my smartphone works as it should I used a BLE HRM belt which was recognized by all three apps.

With your answer I used the 'BlueNRG-1 Flasher' utility to flash the Firmware\BLE_Examples\BlueNRG-1\BLE_SensorDemo.hex file again. Same behaviour: DL1 is flickering but no BLE connection to any of the three apps (BLE HRM belt works fine)...

This is a screenshot after flashing BLE_SensorDemo.hex:

Do you have any further ideas what I could do?

best regards

Wolfgang

Dear

wreinig

,

if you're using the EVAL-IDB007V1Mboard, you have to change the setting for the 32 MHz crystal used in the SPBTLE-1S module. The BlueNRG-1 navigator is preconfigured for the EVAL-IDB007V1 board, which has another crystal (16 MHz).

Please make sure that in your project settings you use this setting:

HS_SPEED_XTAL=HS_SPEED_XTAL_32MHZ

The default configuration in all the projects that you have tried was fora 16 MHz crystal (HS_SPEED_XTAL_16MHZ)and that's why you were not able to make it work with your board.

I don't have anyEVAL-IDB007V1M board to test it myself. Please let me know if this works for you.

Best regards,

Antonio

Hi Aontonio,

i am using the EVAL-IDB007V1M board and Keil V5.

as per your previous discussion ,i change 32 Mhz and it works for "hello World" example.

here, i modify "system_bluenrg.h" file.

But BLE programs are loaded to EVAL-IDB007V1M board but the BLE Android applications not detect.

kindly give the solution...
