[nrf52833]ble_dfu_buttonless_init produces an error4 error when configuring DFU

[K.Kuro]

I configured 2 nus services and DFU in services_init(), But regardless of the order, the third configuration returns ERROR4.If BLE_DFU_ENABLED is not enabled, then everything is fine.

According to some similar questions in the forum, I tried to change the ram space from 0x20002618 to 0x20002AF8, Also made sure to change the NRF_SDH_BLE_VS_UUID_COUNT from 1 to 2 but it didn't work.

I use the nrf52833 with s113 softdevice.

Can someone help me with this problem? Thanks.

Hi,

Which exact function call returns NRF_ERROR_NO_MEM after you increased NRF_SDH_BLE_VS_UUID_COUNT? If we know exactly which function that returned the error, we will know more. And regarding adjustment of RAM space, did you follow the instructions from Adjustment of RAM and Flash memory?
