Hi Sir,
I have 2 devices and follow the following link to change device name.
Re: How to change the device name?
Then I add new BT devices on Windows 7, these two devices show in the same logo and jump back and forth.
Can it be shown as two independent logo?
Solved! Go to Solution.

I was not able to reproduce, I have a BLE name " BLE Prox key fob" greater than 8 and it shows up. It depends on your pc's bluetooth(LE chip and driver) for Windows 7.

Hi Sir,
I have one more question about the add device on Win7.
When the length of the local_name over 8, the device only show Bluetooth LE Device.
Anyway to overcome it?

Hi Sirs,
I do more experiment. It's not only happen on Win7. I use my iphone6 plus and install an App which name is eBeacon. It detect the local name as null.
Experiment 1:
If I define the local name with the length over 8 bytes in the "BLE_PROFILE_CFG", this shows correct.
Experiment 2:
I follow the code on the forum to change the local_name dynamically. See the bold part. One is 7 bytes local name, and another one is 15 bytes local name. The 7 bytes local_name can be shown correct on both Win7 and the eBeacon app. But, the 15 bytes local_name can't be shown correct on Win7 and eBeacon.
The code is as follow:
// Read value of the service from GATT DB.
bleprofile_ReadHandle(HANDLE_MI_MAIN_SERVICE_UUID, &db_pdu);
ble_tracen((char *)db_pdu.pdu, db_pdu.len);
if (db_pdu.len != 16)
{
ble_trace1("\rmicro_inverter bad service UUID len: %d", db_pdu.len);
}
else
{
BLE_ADV_FIELD adv[3];
// flags
adv[0].len = 1 + 1;
adv[0].val = ADV_FLAGS;
adv[0].data[0] = LE_LIMITED_DISCOVERABLE | BR_EDR_NOT_SUPPORTED;
adv[1].len = 16 + 1;
adv[1].val = ADV_SERVICE_UUID128_COMP;
memcpy(adv[1].data, db_pdu.pdu, 16);
// name, TODO: the final version should get the address from microcontroller.
UINT8 *bda = emconinfo_getAddr();
//sprintf(bleprofile_p_cfg->local_name, "SMI%02x%02x%02x%02x%02x%02x", bda[0x05], bda[0x04], bda[0x03], bda[0x02], bda[0x01], bda[0x00]);
sprintf(bleprofile_p_cfg->local_name, "SMI%02x%02x", bda[0x01], bda[0x00]);
BLEPROFILE_DB_PDU p_pdu;
p_pdu.len = strlen(bleprofile_p_cfg->local_name) + 1;
memcpy(&p_pdu.pdu[0], bleprofile_p_cfg->local_name, strlen(bleprofile_p_cfg->local_name));
bleprofile_WriteHandle(0x0016, &p_pdu);
adv[2].len = strlen(bleprofile_p_cfg->local_name) + 1;
adv[2].val = ADV_LOCAL_NAME_COMP;
memcpy(adv[2].data, bleprofile_p_cfg->local_name, adv[2].len - 1);
bleprofile_GenerateADVData(adv, 3);
}
blecm_setTxPowerInADV(0);
bleprofile_Discoverable(HIGH_UNDIRECTED_DISCOVERABLE, micro_inverter_remote_addr);
Any comment and idea?

Is the goal to change the device name dynamically (To change the device's name dynamically
The name needs to be changed in two places per this thread: Re: Unable to change device name
The first one is used during a connection as it allows a client to read the device name value from the GATT database and the second instance is what’s placed in the advertisement packet.
