Adding more characteristics to a custom service is not working on NRF52

[Jayakumar S]

Configuration: nRF5_SDK_13.0.0_04a0bfd PCA10040 ARMGCC

Background:

I have created custom service based on ble_nus service. I have created 4 characteristics with notify support and maximum length of 4 bytes for each characteristics. The service works fine.

Issue: When i try to add the 5th characteristics to this new service, the software is not working. do not even see the log messages from RTT.

Any hint on possible errors would be helpful . thanks

it's not working. We increased attr_tab_size = 0xF00; software restarts now at softdevice_enable at the softdevice call where it hands through the ram base.

Then modify the RAM base as suggested in hundreds of Q&S on this forum as well as Soft Device migration guide...
