Re: ESP32 BLe Password Pairing

Hello, Are you trying to make it so that when you connect to the ESP for the first time, it requests for you to pair your device. Not only that, but it requires a password to pair? This is what you want, right? If so, check out this: Sample code provided by Espressif: https://github.com/espressif/es...

Re: Automatically Reconnect w/Paired Device? esp-idf, BLE (solved?)

Hello, It seems this is not done in the ESP firmware, it is done in the phone application code instead. I'm not sure if this is the correct way to do it or if there are more optimal ways, but here's what I did. In your Android phone application, in the line of code that starts the GATT connection fr...

Re: How to disable/enable BLE? esp-idf

Hello, It took a few tries but I have figured out the proper sequence for enabling/disabling BLE in order to use WiFi. Start the ESP in BLE mode and add a command that will start the WiFi. During WiFi init, do NOT start the WiFi, so don't use wifi_start(). When you call the command to start the wifi...

Re: How to disable/enable BLE? esp-idf

esp_bluedroid_disable(); esp_bluedroid_deinit(); esp_bt_controller_disable(); esp_bt_controller_deinit(); Hello, Thanks for your reply; I am aware of the commands needed to disable BT. What I am having difficulty is *where* to place this code. Currently, the ESP boots to BLE mode, later I call wifi...

How to disable/enable BLE? esp-idf (solved)

Hello, In my project I need to use BLE and Wi-Fi. There's only one radio. I want to disable the BLE to use Wi-Fi. After Wi-Fi serves it's purpose, disable Wi-Fi, enable BLE. If user finished using BLE, disable BLE, enable Wi-Fi. So on and so on. I tried using a command which is called FROM GATT (the...

Automatically Reconnect w/Paired Device? esp-idf, BLE (solved)

Hello,
I am wondering if it is possible to set up the ESP to automatically reconnect with a paired BLE device if the device comes back into range? I thought I saw a setting to do this but I forgot where I saw it or maybe my memory is playing tricks on me?
I am using ESP-IDF, NO Kolban, NO Arduino

Question about BLE and Wi-Fi security

Hello, I am with project implement BLE and Wi-Fi, I habe question about the security of these two. If I set BLE GAP security to MITM and etc. does the ESP take care of encryption or do I have to call that functionality myself? Same for Wi-Fi, I change to WPA2, does it do that encryption automaticall...

How to receive a byte array via BLE???

Hello, I am working on a project in which I want to do some operations over BLE with a gatt client (smart phone). At some point in operation, the ESP can be sent a string from the android app and then the ESP will do some operations using that string. I am wondering if anyone knows a good method to ...

ESP take turns between BLE and Wi-Fi? esp-idf

Hello, I am working on a project in which I want to do some operations over BLE with a gatt client (smart phone). At some point in operation, the ESP can be sent a command to switch to Wi-Fi so it connects to an AP. While it's connected to the AP, the BLE functionality would be disabled. So I am won...
