ANCS library #430

Closed S-March closed 6 years ago

S-March commented 6 years ago

Hi Neil,

I decided to start putting together an ANCS library to use the ESP32 as a smart watch. Right now I'm a little stuck and was wondering if I could pick your brain.

Normally, for ANCS to work, the device must first advertise while soliciting service from the ANCS UUID.

I added the following function to BLEAdvertising so that you can include a service solicitation in the advert packet (this allows the device to show up in the settings panel of an iOS device).

void setServiceSolicitation(BLEUUID uuid);

/**
* @brief Set the service solicitation (UUID)
* @param [in] uuid The UUID to set with the service solicitation data.  Size of UUID will be used.
*/
void BLEAdvertisementData::setServiceSolicitation(BLEUUID uuid)
{
    char cdata[2];
    switch(uuid.bitSize()) {
        case 16: {
            // [Len] [0x14] [UUID16] data
            cdata[0] = 3;
            cdata[1] = ESP_BLE_AD_TYPE_SOL_SRV_UUID;  // 0x14
            addData(std::string(cdata, 2) + std::string((char *)&uuid.getNative()->uuid.uuid16,2));
            break;
        }

        case 128: {
            // [Len] [0x15] [UUID128] data
            cdata[0] = 17;
            cdata[1] = ESP_BLE_AD_TYPE_128SOL_SRV_UUID;  // 0x15
            addData(std::string(cdata, 2) + std::string((char *)uuid.getNative()->uuid.uuid128,16));
            break;
        }

        default:
            return;
    }
} // setServiceSolicitationData

Once you find the device, you can connect in the settings panel. I added the ability to bond in my code, which it does just fine. After bonded, the device shows as connected - perfect.

Here is where I'm stuck. After the device is bonded and connected, the ESP needs to switch out of a server role and into a client role to then subscribe to the ANCS service on the iOS device and read/write to the three characteristics exposed.

I may just be in way over my head, but I can't seem to find a way to force a connection to a white-listed device. Or if I'm already connected, to maintain that connection while I dismantle the server and spin up the client. Any ideas?

Here is the code that I have so far (gets as far as bonding/connecting to device after the advertising stage)

Thanks a ton!

Hi, i have question. Because bluetooth LE security is part of bluetooth v4.2, can you confirm that your iOS device is at least v4.2? If not, can you try to rewrite your code to not use security, or use only encrypted connection?

S-March commented 6 years ago

I’m working with an iPhone 8, so it should b able to handle up to 5.0. I think the 6 was the first iOS device with 4.2. I believe the security is a requirement of the ANCS protocol.

I was thinking about it a bit more during my commute home. Is there a getWhitelistedDeviceAddress call? Or a way to just force the BLEClient to a whitelisted device?

chegewara commented 6 years ago

Can you provide some logs?

Sorry, I should have mentioned: that last log I purposefully forced phone to forget the ESP before rebooting. I wanted to show the whole pairing process. Below is another log. In it, I did the following:

  1. Forced phone to forget device
  2. Booted ESP
  3. Opened settings panel on phone
  4. Found device and hit connect
  5. When pairing pop up showed up, I hit pair
  6. Turned off BT on phone to force a disconnect
  7. Turned BT back on and reconnected to ESP

The second time I connected, I didn't exchange keys or have to acknowledge the pairing. Only the first time. As for why the phone is only showing as 4.0 I'm not sure...

No problem. Looks like device is connected with esp32, which means bonding works good. Now you can try in server callback in onConnect try to create BLEClient and connect to iOS device.

S-March commented 6 years ago

Oh, interesting. I will try that in the morning! Thanks, will report back

S-March commented 6 years ago

Hey @chegewara or @nkolban , any chance you can point me in the right direction to find the remote device address that connected to a server? I think I know where I need to go next, but I can't seem to find how to spin up a client connected to an address I'm already connected to.

Basically, what I'm looking for is something like: "advertisedDevice.getAddress().toString().c_str()"

So I can then take that and pass that to the client for connection.

Thanks!

chegewara commented 6 years ago

If it can be printed out here, then it can be retrieved somewhere: [D][BLEUtils.cpp:1707] dumpGattServerEvent(): [conn_id: 0, remote_bda: AA:AA:AA:AA:AA:AA]

S-March commented 6 years ago

That was my exact thought. But as I was digging through the dumpGattServerEvent(), I couldn't seem to find where the param was sent to it from.

S-March commented 6 years ago

I see this line, where the connect.remote_bda is exactly what I want. I have no idea where param is being passed to it though. esp_ble_set_encryption(param->connect.remote_bda, BLEDevice::m_securityLevel);

chegewara commented 6 years ago

Its passed from low level bluedroid stack as events parameter. Now, as you've found where it can be retrieved from, you can add variable to this class and you will be able to get it when you need it. Its not much work, 2 to 5 lines of code.

S-March commented 6 years ago

I'm sorry if this is a bit of a silly question, I'm just rather new to this. Would I just be adding it to the BLEDevice class?

Something like:

esp_bd_addr_t m_remoteBda;

And then in the BLEDevice::gattServerEventHandler in the ESP_GATTS_CONNECT_EVT case, add something like 

BLEDevice::m_remoteBda=param->connect.remote_bda

Then in the future I can just call BLEDevice::m_remoteBda to put the address where I need it?

chegewara commented 6 years ago

Yes, it sounds good.

S-March commented 6 years ago

So after adding the above, if I call:

Serial.println(BLEDevice::remoteBda.toString().c_str());

I get this error:

error: 'remoteBda' is not a member of 'BLEDevice'

Any ideas?

chegewara commented 6 years ago

Check if this static esp_bd_addr_t m_remoteBda; is private or public. Needs to be public static.

S-March commented 6 years ago

In BLEDevice.h

/**

Wooo! Client is connecting and found the characteristics on phone!

Next step is to ID those notifications and make use of them!

What am i doing wrong?

S-March commented 6 years ago

@krewtib make sure you read through the previous comments. I had to add m_remoteBda to BLEDevice.h If you scroll up a bit you will see where I added it.

chegewara commented 6 years ago

There is no Task class in arduino library. You can try to copy it, but i dont remember if it works in arduino environment.

S-March commented 6 years ago

This is what I used: https://github.com/nkolban/esp32-snippets/blob/master/cpp_utils/Task.h

krewtib commented 6 years ago

Wow. Thanks for so much help.

After making all the changes there is still one error left:

Take a look at the very first post in this thread, I created a setServiceSolicitation() in BLEAdvertising.h

krewtib commented 6 years ago

first i added in BLEAdvertising.h:

in class BLEAdvertisementData {

in public: behind
void setShortName(std::string name); void setServiceSolicitation(BLEUUID uuid);

then i added in BLESdvertising.cpp

behind std::string BLEAdvertisementData::getPayload() { return m_payload; } // getPayload

the routine from your post /**

but still i get a error: ESP32_ANCS:217: error: 'class BLEAdvertisementData' has no member named 'setServiceSolicitation'

Hmm... In my BLEAdvertising.cpp I put the following section of code immediately after the following function. void BLEAdvertisementData::setPartialServices(BLEUUID uuid)

On your phone, forget the device and try repairing it. If it is pairing, it should just work with code as is. What version of iOS are you running? Also when you send an email or text or something to phone, make sure you aren't accidentally reading it or removing it from the notification center. If your phone thinks you saw the notification, it won't forward them to the ESP

I am using iPhone X with IOS 11.3.1. Did as you suggested. Forgot the Device (The Device disconnected properly) Paired again. I did not see any pairing data from onPassKeyRequest. But Device connected. Sent email to phone. Did not read the mail on the phone. Still no respond.

Hmmm... When you paired the device what was the output on the UART stream?

You can also try turning on verbose debugging and seeing what the output is as the connection is taking place.

Great work with the ANCS implementation! I am also trying to run this in the Arduino environment. But even after applying the changes mentioned here, I get tons of errors. For example: 'class MainBLEServer' has no member named 'start' and 'class MyClient' has no member named 'setStackSize' I know that you are not finished with your project yet, but would one of you mind putting the working code and modified library files somewhere on github?

What did the output looks like with your working solution, @S-March? Maybe it is just a problem with Arduino.

@Max K

Maybe also a difference in the ESP32 module? Mine has following print on the lid:

ESP-WROOM-32 211-161007 FCC ID:2AC7Z—ESPWRoom32

I have got 2 of these but none of them work with this sketch. Other sketches are running fine.

My board has the identical print on it. Same ID. But I doubt that this problem is hardware related. There is so much that could be configured incorrectly just because we are using the files from the Arduino library.

I don't have my full project (more than just ANCS) done yet, but I pulled out the ANCS portion of it. This code works for me on an esp32 module. I uploaded it to a module just now to verify and it is working.
