I am trying to connect dualshock3 to stm32f746zg these months. I heard f7 has pins which fit to Arduino so I bought usb host shield 2.0 (for Arduino) and a bluetooth donglel. I know some people use Arduino Ide and run with this shield.but how can I r...
After almost half of a year working with your BlueNRG products I'm still wondering how I am supposed to program it normally.I usually use your examples to make a solution, but it is fairly not enough.Peripheral examples are obsolete and mostly useles...
I looked at BlueNRG 1 and consider what SW there is from ST. Can you point me to a description of what is delivered and the conditions?Do I need to involve 3rd parts here or do ST deliver all and support the BT stack and profiles?
Hi, i`m having an issue with BlueNRG-1. It is configured to advertise every 10 seconds. However, advertising stops after hours, and I can´t connect to the device again. I can see no radio activity on spectrum analyzer when this happens. Any idea abou...
Hello, I have designed a PCB with a STM32F746VET6 microcontroller and LAN8742A physical interface and magnetics. I'm not an expert in Ethernet and I'm not achieving to make it works. I want to validate this design and I'm trying to do a ping to the d...
I have two STM32WB55 nucleo boards, and I have built the BLE_MeshLightingDemo from en.stm32cubewb_v1-4-0.zip (STMCubeWB version 1.4.0). I loaded the stm32wb5x_BLE_Stack_fw.bin, and built the demo with IAR. After factory reset I see the node in the de...
Can I use STUSB4500QTR pin 23 (VREG_2V7) as power source for low power MCU? Max current consumption would be 0.5mA, avg current consumption would be a few uA.

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...
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...
