getServices() causes a crash on a Polar H10 Heart Rate Monitor... but nothing else #239

Open leegs opened 4 months ago

leegs commented 4 months ago

I am trying to pair a Heltec Wireless Stick (V3) to a Polar H10 Heart Rate Monitor and get a crash when calling getServices(). This happens on the example BLEScan and BLEClient examples without any alteration (save the Service UUID of 0x180D and Characteristic UUID of 0x2A37 for the BLEClient example).

I did not have the heart rate monitor when I got the HelTec device, so I familiarized myself with the API by altering the BLEScan example to connect to every address it found to getServices() from each device and getCharacteristics() from each service similar to BLEClient. I ran it in many public places while figuring it out and probably connected to several hundred devices and it worked without a crash.

When the Polar H10 became available, the program immediately crashed. This is a bit of a problem as that is the device I specifically need to use.

The complete serial log with CORE_DEBUG_LEVEL set to VERBOSE from boot to reboot is included at the end of the post. The BLEScan I have been using is unchanged except for the service and characteristic UUIDs and a few Serial.println() calls used to isolate the crash. Nothing of substance is changed. Directly below is an excerpt from BLEScan where the service and characteristic UUIDs are set for the heart rate monitor. 

// The remote service we wish to connect to.
static BLEUUID serviceUUID((uint16_t) ESP_GATT_UUID_HEART_RATE_SVC);
// The characteristic of the remote service we are interested in.
static BLEUUID    charUUID((uint16_t) ESP_GATT_HEART_RATE_MEAS);

It is only possible to verify the serviceUUID is working as expected since the sketch does connect to the Polar H10 as soon as it is found, but does not get past getServices(). The serviceUUID does not seem to be the problem, though.

It appears the call to connect() completes, but the next call to getServices() causes the crash. Below is the verbose output from BLEScan during the call to getServices():

I tried getService(UUID) but got the same crash. The code for getService(UUID) is very basic and returns an element of m_servicesMap suggesting that may be the problem. That variable is assigned in ESP_GATTC_SEARCH_RES_EVT case in gattClientEventHandler(), but no log messages indicate that section of code is ever executed during connect(). The log indicates the crash happens right where the pointer to m_servicesMap is being passed back from getServices() (and getService(serviceUUID) not shown). Perhaps connect() does not populate m_servicesMap and the crash is a result of attempting to return a pointer to the uninitialized m_servicesMap variable?

This is really difficult to explain, though, since an altered BLEScan sketch connected to possibly hundreds of devices and enumerated all services and characteristics without a single crash before getting Polar H10 implying that m_servicesMap does get populated when connecting to a different device.

Below is the log for the call to connect() that seems to show that the ESP_GATTC_SEARCH_RES_EVT case in gattClientEventHandler() is not reached (but cases for ESP_GATTC_REG_EVT, ESP_GATTC_CONNECT_EVT and ESP_GATTC_OPEN_EVT are).

Any help with this would be greatly appreciated. I have some pressure to get these devices connected and working and this bug is far beyond me.

Thank you in advance for any assistance you can provide.

I switched to the espressif/arduino-esp library and it works. Setting the board to "Heltec WiFi LoRa 32(V3) / Wireless shell(V3) / Wireless stick lite (V3)" will allow to build and download.

While the BLE is working perfectly, none of the libraries for either LoRa or the OLED will work with the different board using the espressif/arduino-esp library. I need to get the LoRa radio working. That appears to be fine in the Heltec library.

I believe the quickest solution would be to update the BLE library in Heltec library to the newest from espressif/arduino-esp. (Might as well do the whole system.) I know I would certainly appreciate it.

Thanks.
