Is it possible NRF52 NUS service and Buttonless DFU service work together like the given example, ble_app_hrs, s132_with_dfu?

Hi,

I was trying to add buttonless DFU service along with NUS service. I used SDK v11. Taken the example ble_app_hrs, s132_with_dfu. And added my existing NUS service. I faced a problem that, both are not working together. If i completely disable DFU, NUS service is working. What I should do to make both working together. Any sample code, with NUS and DFU working together?

Thanks in Advance.

There are a few things you could check:

The number of custom UUIDs set in the application.

The required RAM (sd_softdevice_enable() ).

(The attribute table size. Does it change anything if it is increased?)

Only Difference is 2 custom UUIDs, one for NUS and one for DFU. Can I have a sample code working both NUS and DFU ?

Where in the code does your project stop running? During initialization or at a later point in time?

Using nrf connect app, I can just connect it. Showing UART and DFU service. I can't send or receive any data. The advertising LED is keep on running. And suddenly mobile app getting disconnected. Connection not establishing properly.
