I have followed your tutorials on implementing custom service and one on custom characteristics. Everything works when adding only one characteristic. When calling sd_ble_gatts_characteristic_add() the second time I get a terminal error. I have already increased NRF_SDH_BLE_VS_UUID_COUNT to 5 but I have not modified NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE which is 1408. Please see my service code, sdk_config and main.c. I believe the error was out of memory. I need to double check that.
I have modified the RAM_SIZE and RAM_START in the project options (see screen cap). I increased RAM_START after running out of memory.
