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!

Hello, 

Can you please verify that you can see the application in the nRF Connect for Mobile app? All unedited examples should work "out of the box".  I tried the ble_app_gatts_c on my board and then found it in the nRF Connect for Mobile as: Nordic_GATTS.

Have you tried to connect anything else to the Android terminal to verify that it's working?

Best regards,
Oeyvind

 I'm not sure what you mean, can you elaborate? EDIT: These are not a part of the  ble_app_gatts_c example.

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!

Information that you can use SDK unedited is very helpful.

But in my case, it was never detected.

Can it be detected with other samples of SDK?
For example, "ble_app_blinky" or "ble_app_beacon".

As a connection procedure,
1: Write the SDK sample to nrf 52832
2: Supply 3.3 V to nrf 52832
3: Activate "nrfconnect" and SCAN by Scanner
Is not it? Is there anything else I should do?

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.
