I can not connect with BLE(nrf52832)

[y001]

Hello

I am now using nrf52832 and BLE communication with an Android terminal.

BLE communication is a beginner.

I am using nRF_SDK_15.0.0_a53641.

---

Since I programmed the application of android for the time being, I want to make BLE communication with nrf 52832 and confirm that I am connected.

Which of the many SDKs is the most basic program?

I thought that example / ble_peripheral / ble_app_gatts_c is a basic one I wrote to nrf 52832 and executed it, but it was not connected.

Do not you just rewrite LBS_UUID_BASE and LBS_UUID_SERVICE?
If there are other points to be corrected from the initial state and what to do, please point out.

I thought that it might be a problem with the Android application that I created and tried it with an existing nrfConnect application, but it never got connected.

Thankyou!

For this, I suggest you read this: nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_beacon

and then this: nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_hts

For the LBS, it is LED Button Service. Another suggestion is that reading the example description: from here

The nRFConnect application works quite well, I haven't seen any major bug from it so far.

Thank you for reply!

I checked ble_app_beacon.
nrfconnect uses IOS, but there is nothing you can not do without Android?

Although I can not connect even if I tried other SDK examples, it may be that there is some fundamental mistake.

Hi yoko,

Are you using both iOS and Android? You cannot connect to the iBeacon. For other examples, are you sure that your program on the board runs? Some examples you have to reconfigure the linker file.

I tried nrfConnect on IOS. Originally I would like to use Android's own application, but I am using the existing IOS nrfConnect to check the BLE communication on the nrf 52832 side.

It is said that it is necessary to reconfigure the linker file, but is it not necessary to reconfigure at least "ble_app_beacon"?

[y001]

I was checking various things now, but I understood that the sample SDK of BLE is not working.
Is there anything you need to set?

[Duy]

Have you tried the HTS example of the SDK? As I remember that example runs well without reconfiguration of linker SDK 15.2. For your iOS device, before connecting please go to settings-> Bluetooth and remove all devices.

The beacon example runs well, you cannot connect to it because it's the specification.

[y001]

I'm sorry. Because I am using keil LITE, code size is too large to compile "ble_app_hts" and I can not do it.

I tried it with "beacon example", but I did settings-> Bluetooth and remove all devices, but it never got connected.

If you are having issues with code size being too large, then I would suggest either buying a commercial license or develop using free alternatives such as GCC. You can find a tutorial for GCC and Eclipse here.
