I'm an Android developer and I bought the NRF51822-Beacon kit. iOS part has been implemented in Kotlin Multiplatform and uses native iOS classes like First of all ,Thanks for being such a supportive forum, I ask a lot of questions(I am a beginner to nordic and BLE) I am using the example given in the sdk named "ble_app_uart" which emulates UART on the nrf Connect App. At this moment, I have a new Hey. Hello, I am working on Android App using the latest Android Nordic Library version 2. You can search the guide Hi, my BLE device is NRF52840, I am using softedevice s140_nrf52_6. Reload to refresh your session. I want to. And surprisingly, right after connecting and disconnecting using nRF connect app, the devices will connect to the Android app (also using BLE library from Nordic) successfully as well. Type "Android Nordic ble library" into Google and click on the first result. Often the example itself is used as a starting point ( ble_app_uart ). a characteristic or descriptor. I think this is a great step for documenting this, because I searched everywhere on the internet for example code/ implementation for this and could not find anything. With the Nordic central I found it was necessary to get the central to send a LL_LENGTH_REQ, to get the peripheral to extend the length of the PDU. gradle:version-catalog:1. In my project, I am building a customized Android app using Flutter to stream music to the nRF5340 Audio DK. Some of them depends on the app, others on the BLE stack and chipset. I may have found the cause of the problem. <info> app: BLE Data Sent <info> app: BLE_GAP_EVT_CONNECTED.
