Re: Socket issues

@permal could you push your docker image to docker hub and also provide application code so we can reproduce this issue?

Re: Socket issues

Hi Permal, I failed to reproduce your issue: 1. create TCP socket on ESP32 2. do connect to TCP server, server do not reply, let ESP32 re-transmit SYN and timeout (connect() return error, it take around 18 seconds, 3s timeout value * 6 re-transmit times) 3. close socket 4. repeat step 1-3 several ti...

Re: Fetch WiFi Credentinals from iOS connected via Bluetooth

Hi,

You can use Blufi. There's an example in `esp-idf/examples/bluetooth/`.

Re: BLE GATT_Server and GATT_Client at the same time possible?

Hi Lucas.Hutchinson

I think the limitation should be that we can't use (adv) and (scan connect) at the same time. I first let ESP32 work as GATTS, connected by a GATTC (adv auto switched off now), then connect to a GATTS. it works well on both connections with both role.

Re: Changing Supervision timeout on BLE

hi frostyowned,

you may try with the latest IDF. There was a bug that slave can't update conn param.

@Lucas.Hutchinson update conn param should be a function available both for master and slave.

Re: BLE multi-connection procedure

I've tried the following scenarios with GATT service discovery/read/write/notify/indicate: 1. 4 (default max conn allowed in menuconfig) ESP32 (master + GATTC) connected to ESP32 (slave + GATTS) 2. ESP32 (master + GATTC) connect to 4 ESP32 (slave + GATTS) 3. ESP32 (master + GATTC) connect to 2 ESP32...

Re: BLE Secure Simple Pairing

OOB is not ready yet. Only standard pairing methods are supported now. I think OOB pairing is not often used, standard pairing methods are enough for most scenarios. As you mentioned NFC, the most common scenario is that NFC tag just tells the device to perform BT connect to a specific address, not ...

Re: BLE Secure Simple Pairing

Hi, for BLE, you may refer to esp-idf/examples/bluetooth/gatt_secure_server.
there're APIs to set security property and IOCAP, which will be used to compute which pairing method to use.
You may refer to BT Core Spec 4.2, volume 3 part H 2.3. table 2.6, 2.7, 2.8 explains how pairing method is chosen.

Re: Writing tests for a component

Hi, I've wrote some C unit test cases according to the doc http://esp-idf.readthedocs.io/en/latest/api-guides/unit-tests.html. after adding cases, you need to do `make flash TESTS_ALL=1` or `make TEST_COMPONENTS='xxx'` to build unit-test-app and flash to target board. then open the serial console, r...
