I am using bglib to communicate with ble113 with packet mode on and baud rate of 115200.
It is working for all other bglib api calls except for DFU ones.
dfu_reset & system_reset does not trigger a system_boot & dfu_boot event and dfu api calls are getting timed out.
I either never tested the dfu commands or I never succeeded, I think the former. I even commented them out of the code in github! You might have to implement them yourself or at least finish the implementation I started. It might be worth popping onto the Bluegiga docs and forum and check that they actually function and do what you want them to do.
