twi_sw_master and DFU

[Adam]

Hi,

I've combined twi_sw_master and DFU in my project based on nRF51822 Beacon v1.1.0. Now I can't connect to the beacon. The same project only with DFU or only with twi_sw_master works well. Have any of you successfully implemented DFU and twi_sw_master in one project?

@Adam: It's hard to know what went wrong from what you provide. You would need to give some more information on what error you have. I would suggest you to configure the DFU without optimization (level O0), update ROM start address (to give more space for bootloader) and NRF_UICR_BOOT_START_ADDRESS to match with the new address. After that you should be able to run the DFU in debug mode and find what cause the issue.
