Android nRF_UART Multiple Conection

[Bruno]

Hi,

I'm developing an application on Android based on nRF_UART apk source, but i'm having trouble in connecting to two BLE devices. Actually, i think i could manage to connect to two devices, but the problem stands on Tx Characteristic notification, it looks like i'm receiving the same message from both devices, which is not supposed to happen, each device should send a different message.

Is there any help or guide through connecting to more than one BLE device at the same time?

Specs:

- using Android Studio v3.3.2

- source modified from nRF_UART

- Trying to connect to two NRF52832 BLE GATT Server

- The application consists in basically "ask" BLE's device for data and it "sends" it back through NUS TX and RX characteristics, then, the app process both device's data and shows it on screen.

- Just to point out: I cannot send my data over advertising, i need to stabilish a connection (because of the application format).

My guess is something related to the GATT layer wich does not allow more than one instance of the characteristics 

Here is a screen shot of my log cat while trying to connect to 2 BLE devices

If someone could help me i'd be very glad!

Thanks in advance,

Bruno.

We ended up reformating the application, now data will be sent via advertising....even though i think this is not the intend which the advertising role was designed for....well, thanks for your answers!
