Cannot initialize CyclingPower service

[Toyman]

I have developed CyclingPower SIG service based on (a) CSCS example and on (b) old file found here, at Devzone.

It used to work, but then something happened and I can't make it work again. I am attaching *.h and *.c files and below is my init routine:

static void cps_service_init(void){

uint32_t err_code;
ble_cps_init_t cps_init;

memset(&cps_init, 0, sizeof(cps_init));

cps_init.evt_handler = NULL;
cps_init.feature = BLE_CPS_FEATURE_WHEEL_REV_BIT | BLE_CPS_FEATURE_CRANK_REV_BIT |
BLE_CPS_FEATURE_MULTIPLE_SENSORS_BIT;

BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cps_init.cp_meas_attr_md.cccd_write_perm);
BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cps_init.cp_feature_attr_md.read_perm);

cps_init.ctrlpt_evt_handler = sc_ctrlpt_event_handler;
cps_init.list_supported_locations = supported_locations;
cps_init.size_list_supported_locations = sizeof(supported_locations) /
sizeof(ble_sensor_location_t);

sensor_location = BLE_SENSOR_LOCATION_LEFT_CRANK;
cps_init.sensor_location = &sensor_location;
BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cps_init.cp_sensor_loc_attr_md.read_perm);

err_code = ble_cps_init(&m_cps, &cps_init);
APP_ERROR_CHECK(err_code);
}

Hi,

It used to work, but then something happened

What is the last thing you changed in the code?

Could you debug the code and see what error code you get?

[Toyman]

Well, it is not that simple unfortunately. I completely reverted back all (small) changes I made, but with no success.

I don't get any errros, both at the compile stage and in the rutime.

I increased log verbosity level to 4, but no errors. At connect, I get 0x50, 0x12 and 0x52 statuses.

Where can I get their meaning?

I also tried to increase NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE to 2000, it didn't help

Symptom I have: the service is not listed in nRF Connect after the connection. All other services are listed, with their characterics.

The service IS listed in adv packet, but thats another story.
