time out when DFU fail

[MR.liu]

Hi ALL: now the time out when dfu fail is 120s,It's a little bit long for us，can i reduce it ？how much is the least?

We do not have a specified minimum time timeout interval, but I think that you should be able to set it to 30s without running in to any issues. Generally, I would just test som different values and if you dont see any issues, then you're ok.

Best regards

YEs, in a connection the maximum payload of a BLE packet is 20 bytes, so an image of 127 kB will be about 6503 packets. The dfu timer will be reset when a data packet is received, so it will not timeout unless the connection is broken.
