How do I fix the failed attempt to add Characteristic to aci_gatt_add_char() in BlueNRG-2？
I used BCN002V1D development board.When I used the BLE Chat Demo project, I added Characteristic to the original service.There should have been no problem, but when it was run, it got an error code 0x47.
The requested operation violates The logic of The called layer/function or The format of The data to be processed during The operation.
#define BLE_STATUS_ERROR ((tBleStatus)(0x47))
I think my format is referring to the other Demo project, should be no problem.I wonder if configuration is needed elsewhere?
Here is the code for the function that ran wrong. I added the italicized part.
uint8_t Add_Chat_Service(void) {
uint8_t ret;

const uint8_t uuid[16] = { 0x66, 0x9a, 0x0c, 0x20, 0x00, 0x08, 0x96, 0x9e, 0xe2, 0x11, 0x9e, 0xb1, 0xe0, 0xf2, 0x73, 0xd9 };

Osal_MemCpy(&service_uuid.Service_UUID_128, uuid, 16);
ret = aci_gatt_add_service(UUID_TYPE_128, &service_uuid, PRIMARY_SERVICE, 6, &chatServHandle);
if (ret != BLE_STATUS_SUCCESS)
goto fail;
Osal_MemCpy(&char_uuid.Char_UUID_128, charUuidTX, 16);
ret = aci_gatt_add_char(chatServHandle, UUID_TYPE_128, &char_uuid, 20, CHAR_PROP_NOTIFY, ATTR_PERMISSION_NONE, 0, 16, 1, &TXCharHandle);
if (ret != BLE_STATUS_SUCCESS)
goto fail;
Osal_MemCpy(&char_uuid.Char_UUID_128, charUuidRX, 16);

printf("Chat Service added.\nTX Char Handle %04X, RX Char Handle %04X\n", TXCharHandle, RXCharHandle);
return BLE_STATUS_SUCCESS;
fail: printf("Error while adding Chat service.\n");
return BLE_STATUS_ERROR;
}
The operation results are as follows:
BlueNRG-1 BLE Chat Server Application (version: 1.0.0)
aci_gatt_init() --> SUCCESS
aci_gap_init() --> SUCCESS
aci_gatt_update_char_value_ext() --> SUCCESS
debug3
Error while adding Chat service.
Error in Add_Chat_Service 0x47
CHAT_DeviceInit()--> Failed 0x47
If I remove the first code that added Characteristic, the code I added will work fine.But when I removed the second code that added Characteristic, the service wasn't created properly.
How to solve this problem？
