SDK 11.0.0, S132 v2.0.0, nRF52.
I have searched through the many questions already on the dev zone on this topic, but cannot solve my problem. I tried adding the dfu service to a ble project that already contained ble nus and ble_rscs services. When I add the dfu service, the device does not advertising. Through debugging, I found that the dfu_init function, which is the last service initialized in services_init, returns a no memory error.
From what I can see on the dev zone, there are two options:
- Increase the attr table and then increase the the start addr of RAM, then decrease the size of RAM accordingly.
- Use ble_gatts_vloc_user instead of ble_gatts_vloc_stack, and make sure the attributes are declared as either a static local or global variable.
When I try the first option, I change SOFTDEVICE_GATTS_ATTR_TAB_SIZE to 0x1080 (from 0x580), and I change the RAM start to 0x20002580 (from 0x20002080) and the RAM size to 0xDA80 (from 0xDF80). Despite these changes, I still get the no memory error (0x0004).
When I try the second option, I change the nus attributes that are assigned to ble_gatts_vloc_stack to be assigned to ble_gatts_vloc_user, such as: cccd_md.vloc = BLE_GATTS_VLOC_USER and attr_md.vloc = BLE_GATTS_VLOC_USER. When I try it this way, I get an invalid params error from the function that adds the rx_characteristic (0x0007)
Understandably, when I comment out the initialization for the nordic uart service, the project works just fine.
Were my attempts at a solution correct in and of themselves? Is there something I am missing?
