BlueNRG-2 - how to switch on the LS RO oscillator with working LS XO oscillator without external reset (RESETn pin) or power cycling after firmware updating over "OTA"? The chip is BlueNRG-232 (it reports a "chip version" 1.0.0).

We use BlueNRG-2 in custom sensor. The original firmware uses LS XO (32 kHz crystal). But we need to have ability to choose the LS "RO" or "XO" after firmware updating over "OTA" (FOTA). It seems that if LS XO has been turned on once then the LS RO i...

BLE Mesh on BlueNRG-1 w/Proxies?

I have an existing phone app (using the traditional GATT system), and I would like mesh-enable my products so that if the products can see each other, then the phone can connect to and control any node (so, not so much an automation system but a rela...

Are ST Micro BLE solutions susceptable to SweynTooth issues?

Our Director of Quality made us aware of a BLE security issue called Sweyntooth. See: https://gbhackers.com/sweyntooth/ and https://www.wired.com/story/bluetooth-flaws-ble-internet-of-things-pacemakers/  Per the articles, it looks like STMicro's inst...

Nucleo L152RE and S2LP: debugger connection lost with using sigfox

I used nucleo-L152RE and S2LP S2868A1. My device was connected with the Sigfox network. I ran the application Sigfox push button demo. When I want to debug the code and pushed the button, the console reported to me this following message :Target is n...

[BlueNRG-MS] X-CUBE-BLE1 stack code messes up __packed macro

Hello! I am using STM32L476 with X-NUCLEO-IDB05A1 (SPBTLE-RF) and X-CUBE-BLE1 v4.4.0 and STM32CubeIDE v1.2.1 on Windows 10 x64.I was implementing a custom HID-over-GATT Profile device using the X-CUBE-BLE1 examples.So as I did before for USB HID I wo...

We are implementing the SPBTLE-1S as an off-the-shelf BLE solution, and we can't find any documentation about the default Mode, as apparently it can operate in 4 different interface Modes: "000", "001", "100", and "010", as per the data sheet.

Ideally, I need it to work in serial1 or Mode "001" on boot.  Is this indeed the firmware default? As an integrated BLE module I would expect it to work immediately, i.e. plug and play but in which mode? I assume I can change firmware and/or registe...
