About initialization problem [Copy link]

 

I would like to ask what is wrong with my initialization that causes the Bluetooth to not turn on the receiving function and report the error failed:0x48. Specifically, I would like to ask where the problem is.

void Add_Server(void)
{
uint8_t status = BLE_STATUS_SUCCESS;

const uint8_t uuid[16] = {0x66,0x9a,0x0c,0x20,0x00,0x08,0x81,0x98,0xeb,0x11,0x8b,0x7d,0x20,0xd1,0x69,0x86};
const uint8_t charUuidTX[16] = {0x66 ,0x9a,0x0c,0x20,0x00,0x08,0x81,0x98,0xeb,0x11,0x8b,0x7d,0x21,0xd1,0x69,0x86};
const uint8_t charUuidRX[16] = {0x66,0x9a,0x0c,0x20,0x00,0x08,0x81,0x98,0xeb,0x11,0x8b,0x7d,0x22,0xd1,0x69,0x86};

Osal_MemCpy(&service_uuid.Service_UUID_128, uuid, 16);
status = aci_gatt_ add_service(UUID_TYPE_128 ,&service_uuid ,PRIMARY_SERVICE , 0x04 ,&ServHandle);

* The one indicated in red, if 0x04 is used, Bluetooth has no reception, but transmission and service are normal. If 0x06 is used, all three are wrong.

if (status != BLE_STATUS_SUCCESS) {
PRINTF("aci_gatt_add_service() failed:0x%02x\r\n", status);
APP_FLAG_SET(APP_ERROR);
}else{
PRINTF("aci_gatt_add_service --> SUCCESS\r\n") ;
}

Osal_MemCpy(&char_uuid.Char_UUID_128, charUuidTX, 16);
status = aci_gatt_add_char(ServHandle ,UUID_TYPE_128 , &char_uuid ,20 ,CHAR_PROP_NOTIFY ,ATTR_PERMISSION_NONE ,0 ,16 ,1 ,&TXCharHandle);

if (status != BLE_STATUS_SUCCESS) {
PRINTF("aci_gatt_add_TXchar() failed:0x%02x\r\n", status);
APP_FLAG_SET(APP_ERROR);
}else{
PRINTF("aci_gatt_add_TXchar --> SUCCESS);
}

Osal_MemCpy(&char_uuid .Char_UUID_128, charUuidRX, 16);
status = aci_gatt_add_char(ServHandle ,UUID_TYPE_128 ,&char_uuid ,20 ,CHAR_PROP_WRITE|CHAR_PROP_WRITE_WITHOUT_RESP ,ATTR_PERMISSION_NONE ,GATT_NOTIFY_ATTRIBUTE_WRITE ,16 , 1 ,&RXCharHandle);

if (status != BLE_STATUS_SUCCESS) {
PRINTF("aci_gatt_add_RXchar() failed:0x%02x\r\n", status);
APP_FLAG_SET(APP_ERROR);
}else{
PRINTF("aci_gatt_add_RXchar --> SUCCESS);
}
}

Shouldn't this number be a bit larger? I changed it to 7 and it reported an error of 0x48 when adding a server. Is this related to the GATT initialization function in the example?

I modified the Project\BLE_Examples\BLE_MS_Formula routine because this routine originally did not have a receiving characteristic.

The error 0x48 corresponds to insufficient memory. Check if there are any other problems. To rule out the Max_Attribute_Records problem, you can try to change Max_Attribute_Records in the official example to see if the same error is reported.

Look at my last reply, the picture names are different, one is 0x04 and the other is 0x06

I don't quite understand your 4 pictures. Is there no 0a001 service at 0x06?

Why don't you send me this code and I'll try it for you?

Yes, I just want to express that there is no service 0a001 at 0x06, and I can't add another UUID

The code is the set_database function of the \BlueNRG-1_2 DK 3.2.1\Project\BLE_Examples\BLE_MS_Formula routine. Because this routine does not have a received UUID when used as a master-slave, I have not been able to get an additional RX UUID.

The service database is static memory in the protocol stack, rather than dynamically allocated when add_service is called.

Therefore, before add_service, when initializing the protocol stack (BlueNRG_Stack_Initialization), you need to clearly indicate the size of the entire database - just configure the following macros correctly according to your needs:

NUM_GATT_ATTRIBUTES
