So, I want to do BLE DFU from one nRF52 MCU to another nRF52 MCU. The start point for me was this:
- put SMP server sample on one nrf52dk (this device is advertising)
- put Bluetooth: Central DFU SMP sample on other nrf52dk
- they connect by default because the board that is advertising (the first one) has an SMP service.
- I can send echo command over BLE SMP
I am using NCS 1.5.0 on Ubuntu 18.04 LTS with two nrf52dk_nrf52832
Best regards,
Vojislav.
