AOSP 9
I am trying to develop a BLE GATT server app for khadas vim3 to act as a peripheral device, so i got an custom app which when installed on pixel4 or other devices ble advertising correctly but when i install same app on kvim3 advertisement is not happening. does kvim3 has ble advertisement capabilities for running a GATT server application.
I don’t quite understand what your advertisement means. Is it an apk broadcast?
Hi @xiong.zhang, thanks for your reply.
Since I’m experiencing issues with Classic Bluetooth communication between my control mobile phone and the KVIM3, I’ve decided to use KVIM3 as a BLE peripheral. By connecting it to my control mobile via BLE, I can exchange small amounts of data wirelessly to manage app launching features and other functionalities on the KVIM3 from my custom app on the control Android mobile, but KVIM3 not able to advertise small custom server data or behave as a GATT client.
Using the nRF Connect app, I checked the BLE capabilities of the KVIM3 and found that while it supports peripheral mode, but interestingly it is not able to start advertising. Whenever I try to start advertising, it gives an error message.
failed to start advertising with errorcode: 2
This is the first time we have seen you mention this issue. We have never dealt with this issue before. Our Bluetooth supports some relatively simple basic uses. I wonder if the following link can help you.
