Hello. We have several questions about the operation of your Rak 11720 module.
How to determine that the data via ble has been transmitted and the sending is complete?
What is the maximum data size that can be transmitted using the api.ble.uart.write function?
We have written a test about the transmission and reception of data via ble. This situation greatly slows down the data transfer in figure. Is it possible to solve this problem?
Hello, the problem remains quite relevant for me, could you help?
The most important thing is to determine the success of sending a packet via BLE uart, how can you determine that the packet was transmitted successfully?
I am checking now with the team about the limit of payload size.
As for confirmation, if there is no return acknowledgement from the APP side you cannot guarantee reception. In addition, you can consider to add simple checksum as well to validate that payload was received reliably.
