Yes, all 10 boards are Lolin32 lite.
I meant to say "from different retailers." All boards are from the same vendor.

Re: Issue with 1 out of 10 touch buttons
I have looked at this from all sides. I tested with 10 different ESP32 boards, old and new and from different vendors. Problem remains: depending on what is powering the ESP32 board via USB port, one specific touch sensor (T1) may not receive values. It is not a single, malfunctioning board causing ...

Issue with 1 out of 10 touch buttons
This issue only manifests itself with touch button 1 (T1). I never see it happen with any of the other 9 touch buttons (T0, T2, T3 ... T9). On my dev-board (Lolin32 lite), T1 is made available on the same pin as GPIO 0. When T1 malfunctions, touch_pad_read(1,&val) will return either 0 or 1 for val. ...

Classic Bluetooth availability
Urgent: When will Classic BT support become available for ESP32?
While it isn't available yet, why do the BLE samples enable Classic BT? Could power consumption be reduced for BLE-only apps, by not enabling Classic BT?

Re: Cannot get all characteristics of a service
Hi james89, the exact same thing is happening to me, too. But it only happens in combination with certain peripherals. For instance, it never happens with Android (Bluedroid) based peripherals. Android peripherals always let my ESP32 fetch all characteristics. The problem occurs when I connect my ES...

Re: Bluetooth crash dump trace
Finding: The more log categories I raise (from WARN to DEBUG) in bluedroid/include/bt_trace.h, the more random "LoadProhibited" crashes do occur at runtime. When I bring everything back down to the original WARN level, this appears to solve the issue. But I think this may be only because WARN and ER...

Re: BLE connect to non-advertising peripheral
By looking at my logs, I more and more get the impression that "Gatt over BR" (Core spec 4.2, Vol 3, Part G, sect 9) may be fully implemented already. And that all I need to do, to fix my HCI connection problem, is to PAIR! the devices. Can someone pls help me write a simple auto-pairing app? (I do ...

Re: BLE connect to non-advertising peripheral
What is the exact situation with BT classic on ESP32 currently? It appears to be working partly. Status 0x08 in the error message referenced above ("btm_read_remote_features_complete failed (status 0x08)") stands for HCI_ERR_CONNECTION_TOUT. Is a HCI connection timeout an expected callee side behavi...
