Reading characteristic values inside BLE_client notifyCallback

[ahue32]

I have two Adafruit Huzzah32 Feather boards with ESP32 modules on them. I want to connect both of them, one as a server sending data via notifications, the other one as a client receiving all changed values.

Code for server (I changed the BLE_uart example a little):

Code: Select all

/*
    Video: https://www.youtube.com/watch?v=oCMOYS71NIU
    Based on Neil Kolban example for IDF: https://github.com/nkolban/esp32-snippets/blob/master/cpp_utils/tests/BLE%20Tests/SampleNotify.cpp
    Ported to Arduino ESP32 by Evandro Copercini

   Create a BLE server that, once we receive a connection, will send periodic notifications.
   The service advertises itself as: 6E400001-B5A3-F393-E0A9-E50E24DCCA9E
   Has a characteristic of: 6E400002-B5A3-F393-E0A9-E50E24DCCA9E - used for receiving data with "WRITE" 
   Has a characteristic of: 6E400003-B5A3-F393-E0A9-E50E24DCCA9E - used to send data with  "NOTIFY"

   The design of creating the BLE server is:
   1. Create a BLE Server
   2. Create a BLE Service
   3. Create a BLE Characteristic on the Service
   4. Create a BLE Descriptor on the characteristic
   5. Start the service.
   6. Start advertising.

   In this example rxValue is the data received (only accessible inside that function).
   And txValue is the data to be sent, in this example just a byte incremented every second.

I am able to read the characteristic value the first time outside of the callback, but when I try to read it inside nothing happens afterwards.

This is the log of the server:

Is it possible at all to read characteristic values inside of notification callbacks? I am able to read every characteristic value if I do it in loop() but that does not make sense to me. What do I need to do to make it work?

[chegewara]

This is what you are sending all the time in loop from server thru notifications:

Code: Select all

    pCharacteristic->setValue("Hi");
    pCharacteristic->notify();
    

As you can see your value is constant and its confirmed by this log:

Code: Select all

[D][BLECharacteristic.cpp:629] setValue(): >> setValue: length=2, data=4869, characteristic UUID=6e400003-b5a3-f393-e0a9-e50e24dcca9e

Capital 'H' is 0x48 and 'i' is 0x69 in ASCII table.

Now what client is reading is here:

Code: Select all

Hi

Here you should receive and print notification value:

Code: Select all

[D][BLERemoteCharacteristic.cpp:173] gattClientEventHandler(): Invoking callback for notification on characteristic Characteristic: uuid: 6e400003-b5a3-f393-e0a9-e50e24dcca9e, handle: 42 0x2a, props: broadcast: 0, read: 1, write_nr: 0, write: 1, notify: 1, indicate: 0, auth: 0

and you are receiving it but you have commented out this line:

Code: Select all

  //Serial.println(pBLERemoteCharacteristic->readValue().c_str());

[ahue32]

and you are receiving it but you have commented out this line:

Code: Select all

  //Serial.println(pBLERemoteCharacteristic->readValue().c_str());

When I comment in this line the log looks the same and nothing happens afterwards. The point is, if

Code: Select all

std::string value = pBLERemoteCharacteristic->readValue();

is commented out, the log from the client looks like this:

Code: Select all

...

There is a notification once every second, but if I read the value there is just one received notification and nothing afterwards.

This log looks like different. As you can see in first client log there was this log line:

Notify callback for characteristic 6e400003-b5a3-f393-e0a9-e50e24dcca9e of data length 2

and it comes from this part of code:

Code: Select all

static void notifyCallback(
  BLERemoteCharacteristic* pBLERemoteCharacteristic,
  uint8_t* pData,
  size_t length,
  bool isNotify) {
    Serial.print("Notify callback for characteristic ");
    Serial.print(pBLERemoteCharacteristic->getUUID().toString().c_str());
    Serial.print(" of data length ");
    Serial.println(length);

Which means notification works and is handled. Now you just uncommented one line and notifyCallback seems its not to be called. That odd. Im running just now very similar code. My code is compilation BLE_notify with BLE_client into one application and everything is working. Only difference can be in ESP32BLE library version, because im using library cloned from here https://github.com/nkolban/esp32-snippets and prepared to work with arduino and im can guess you are using library gathered with library manager in arduino-ide. I will try to make test with that library little bit later today.

I'm using a workaround now where I set a flag inside the callback and check the value of the characteristic in loop. As I use core 0 only for Bluetooth the response time is ok.

I had a look inside BLERemoteCharacteristic.cpp and found the following problem:

In the 'readValue()' method, there is a call to take the semaphore and afterwards one to wait. It seems that the wait is never called. As far as I understand semaphores, it is because in 'm_semaphoreReadCharEvt.take("readValue");' there is an infinite blocking of the semaphore and it never gets released. If I add 'm_semaphoreReadCharEvt.give();' before 'm_semaphoreReadCharEvt.wait("readValue");' then it works.

Code: Select all

/**
 * @brief Read the value of the remote characteristic.
 * @return The value of the remote characteristic.
 */
std::string BLERemoteCharacteristic::readValue() {
	ESP_LOGD(LOG_TAG, ">> readValue(): uuid: %s, handle: %d 0x%.2x", getUUID().toString().c_str(), getHandle(), getHandle());

	// Check to see that we are connected.
	if (!getRemoteService()->getClient()->isConnected()) {
		ESP_LOGE(LOG_TAG, "Disconnected");
		throw BLEDisconnectedException();
	}
	
	m_semaphoreReadCharEvt.take("readValue");
	ESP_LOGD(LOG_TAG, "next1"); \\ Messages to find out when exactly the program stops. 
	// Ask the BLE subsystem to retrieve the value for the remote hosted characteristic.
	// This is an asynchronous request which means that we must block waiting for the response
	// to become available.
	esp_err_t errRc = ::esp_ble_gattc_read_char(
		m_pRemoteService->getClient()->getGattcIf(),
		m_pRemoteService->getClient()->getConnId(),    // The connection ID to the BLE server
		getHandle(),                                   // The handle of this characteristic
		ESP_GATT_AUTH_REQ_NONE);                       // Security
	ESP_LOGD(LOG_TAG, "next2"); \\ Messages to find out when exactly the program stops.
	if (errRc != ESP_OK) {
		ESP_LOGE(LOG_TAG, "esp_ble_gattc_read_char: rc=%d %s", errRc, GeneralUtils::errorToString(errRc));
		return "";
	}
	ESP_LOGD(LOG_TAG, "next3"); \\ Messages to find out when exactly the program stops. 
	m_semaphoreReadCharEvt.give(); \\ I put that in and now it works
	// Block waiting for the event that indicates that the read has completed.  When it has, the std::string found
	// in m_value will contain our data.
	m_semaphoreReadCharEvt.wait("readValue");
	ESP_LOGD(LOG_TAG, "next4"); \\ Messages to find out when exactly the program stops. 
	ESP_LOGD(LOG_TAG, "<< readValue(): length: %d", m_value.length());
	
	return m_value;
} // readValue

I don't know if this 'm_semaphoreReadCharEvt.give();' may lead to any other bad behaviour. If you encounter anything that is strange or know a reason why this is not an adequate solution please let me know.

Solution worked for me. Thnx!
