Dear Developers! I'm a newbie in nrf51822 My Project needs to change between central and peripheral role. How can I apply OTA DFU with S130 soft device ?. In nrf51822 DFU example I can only find the nrf51822 S110 example. Thanks for reading.

If you download SDK 9.0.0, you can find example code for a S130 bootloader (dual_bank_ble_s130).
