I create a large BLE hid report map, when regmap length=575, in hids_init() function will report fatal error, trace find in rep_map_char_add(), err_code=12. [NRF_ERROR_DATA_SIZE].
after I remove part of the report map. regmap length=504, then no problem.
Try to increase NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE from 1408 to 1600, still have this problem.
Andy limitation of the size for hid report map ? How can I expand it ?
SDK based on nRF5_SDK_17.1.0_ddde560.

From the Human Interface Device Service 1.0 spec, https://www.bluetooth.com/specifications/specs/human-interface-device-service-1-0/ , page 16:
Also, in the Bluetooth core specification it states that the maximum length of an attribute value should be 512 octets (bytes).
