i'm trying to modify a device with Ble stack inside a kw41z that use wireless uart nxp demo. My fw is ok and it "speaks" with a smartphone app without problems.
Now i need to program more of one device (currently only two devices) at the same times with two different smartphone that use the same app.
In the first step i changed the "shortened local name" in the gapAdStructure_t inside app_config.c file. I also changed the "public device address"in gBDAddress_c array (BD_ADDR macro).
With this mods the app is able to view the different devices with the same firmware but it works bad. For example, if i switch on both devices and if i connect a device with app, when i switchoff the other, the first does a disconnection from the app.
i'm trying to change the uuid128 of the uuid_service_wireless_uart but i'm not shure if this a correct procedure.
How can i do?
