I have to transfer a text file (about 150Kbyte) via UART1 to a Q2687 modem, using FCM.
Everything works well.
The only problem is the time taken for the transfer. I noted that data are transfered at 1Kbyte/sec,
despite the uart1 is configured at 115200Kbit/sec (approx 11,5Kbyte/sec).
If I print the DataLen parameter on the Data Callback of FCM I noted that most of the time there is only 1 byte.
This leads to increase of transfer time.
Is there some parameters in FCM to change uart buffer or other tricks to speed up the process?
