Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Back in May of 2022, I purchased a number of BlueNRG-LP-DK development boards (STEVAL-IDB011V2-C) for Bluetooth Low Energy development. Things went fine (in a manner of speaking of course) .Recently I tried to use these boards with its RTC (Real Tim...
Hi, I am evaluating to use the ST8500 module as alternative part of the ST7538Q.In our application we have a custom protocol over power line with FSK modulation.Looking all the documentation related to ST8500 I found that it is possible to configure ...
Hello all,I am working on creating a secure IoT device. The device is configured as MQTT client which will be sending sensors data to the sever over MQTT. I have implemented encryption using mbed-TLS where I confirm server's authenticity with server ...
Hello ST Community,I am working on a project that involves implementing the STUSB1602 to act as a USB Power Delivery (PD) source while maintaining USB 2.0 data passthrough functionality. I would like to know how to best approach this design and which...
Hello,When I try to set advertisement delay more than 10000ms, the function aci_gap_set_advertising_configuration return an error 0x82 (BLE_STATUS_INVALID_PARAMS). According to the function declaration, it must be ok:/* .... * @param Primary_Advertis...
Posted on August 14, 2015 at 19:20So if I want to hop to various frequencies I need to calibrate the VCO each time. That's fine and expected. The SPIRIT1 has a fantastic auto calibration time of only around 50us - one of the features that make it at...
Hello! The task is to implement a device with two-port Ethernet. To do this, I developed a circuit, connected the STM32F207 controller to the KSZ8863RLLI Ethernet transceiver via RMII. The controller and the transceiver are connected according to the...
Hi folksI am currently trying to communicate with the TLV493D-A1B6 3D hall sensor. As board, I'm using the NUCLEO-F103RB. To make sure I didn't mess up any connections or anything else, I verified my setup with an ADS1015 adc which I can read out ove...
Dear everyone,I'm trying to use a SX1280 for RF connectivity.My dev board is the official... the SEMTECH "SX1280ED1ZHP", it's included a nucleo + daughter board with SX1280.My diffculty is that a not able to read correctly a register with a know valu...
Hi everyone,I'm currently using an STUSB1700 as a 5V 3A power source for one of the USB ports in my project. I'm able to draw up to 2.7A with Apple devices (iPhones and iPads) on that port. Using the STUSB GUI, I can connect to the STUSB1700 via I2C ...
