All,
We have an issue with the data transfer rate between a device that uses a nRF52480 (Rigado-340).
We are sending a number of data chunks, approximately 400, where each chunk is 32634 bytes long.
We call the SoftDevice and pass in a buffer containing the data.
The data is received by an android app.
The issue we have is there appears to be a delay between the 244 byte long packets. Below is an extract from a log running on he receive side.
The timestamp shows each 244 bytes takes approximately 28ms and 43ms before the next 244 bytes are received.
We need to cut this down to below. 2ms.
Any ideas where we are losing time? Or anyway we can narrow down to the problem area?
