Interface and connectivity ICs

bluenrg2 always crash with ac contactor

i use bluenrg2 as main mcu , to control a ac 220v ac contactor , the main logic isbluenrg2 -> Optocoupler -> DC 12V relay -> AC 220V ac contactorIf i open/close, the bluetooth will disconnect and will crash very often. Is it not suitable for my case

Hi all, I want to interface STM32f407 VGT (STM32F4 DISCOVERY) with CC2500 using SPI. Please help me for this. Thanks

BlueNRG-2: What do I need to do to adopt zephyr's bluetooth stack?

I am using zephyr RTOS on BlueNRG-2. Now I have to use default bluetooth stack. Zephyr has a pretty good bluetooth stack. It would be nice to be able to use it's bluetooth implementation instead of ST's. That way my application can be easily ported o...

Which STM BT IC is recommended for BT audio streaming?

I would like to create a BT audio streaming device, i.e, bluetooth loudspeaker. This device has a few LEDs and a display. Any Android/iPhone device can connect to it and transmit audio. I also want to add some private GATT characteristics in order to...

I am trying to decode S2LP transmission using software defined radio. I am able to transmit between S2LP devices but the message is not being decoded by my SDR. Any help from anyone with experience would be great.

The software I am using is SDR# and soundmodem.

Need information about interface with TDA7703, the datasheet don't gives an clear example about the interface between the TDA7703 and a microcontroller.

Hi,I want to use an USB device in order to load the .elf file via USB on STM32F746.How can I do this?Best Regards

I am currently using the BlueCoin for my project, will the BLE module on the BlueCoin work with PC? Or only mobile phones. I encountered an issue where a pin code is required to connect the BlueCoin in the bluetooth settings.

Using the STM32L476RG-Nucleo dev board with the Wi-Fi extension (X-NUCLEO-IDW01M1 ) Been following the Step-by-Step Guide: SPWF0xS firmware upgrade over UART (attached PDF) found in the STM32CubeExpansion_WIFI1_V3.1.1

I need SPWF FW version v1.1.0 to flash onto the board (pg.8 Select the binary file to program the Flash) have been unable to locate SPWF01S-160129c5bf5ce-RELEASE-main.bin or any updated version.
