THE MOST IMPORTANT EXPERIENCE
HOW DOES THE FILE
TRANSFER WORK WITH BLE?
Each file has to be split into smaller chunks - packets before we can send it to the device. There are two ways of sending it, with and without a response. First one is much slower, as an app has to wait for a confirmation after each packet, so we had to use the second one if we wanted to achieve shorter transfer times. When you are sending packets without response, the key is in fine-tuning the amount of data that is being sent, to not overload the device, but to use the possible transfer in the most efficient way. During that process, we’ve learned a lot, and down the road, both platforms were sending files in satisfying time
