Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I am a student who is currently doing his bachelor thesis. My job is to control two microcontrollers (Nucleo-STM32F411RE) via Bluetooth (X-Nucleo-BNRG2A1) in order to transfer parameter values for a system. The idea was to connect the microcontroll...
When I'm sending data from computer it works perfectly- data is sent and STM's response is received over UART in RealTerm. However switching to bluetooth module and sending and receiving data from android app doesn't work as expected. For now I want ...
Posted on August 08, 2017 at 14:40Hi,I have the ST S2-LP transceiver both transmitting and receiving just fine however i'm struggling to put the chip into a continuous wave mode.. from reading the data sheet i have configure the following : To set...
Hello,I have been working for a week now on USB-C Power Delivery Library for STM32G0 but I am facing some problems to communicate with other devices. I want to setup a Dual Role Power (DRP) communication with a power bank also supporting DRP.I based ...
I have been looking for PSD813F2A-90J from many website and suppliers, such as :https://www.firstbom.com/pro/stmicroelectronics/psd813f2a-90j/5183742https://www.firstbom.com/pro/stmicroelectronics/psd813f2a-90ji/5183743But the information about it ...
Hi there!What is the correct procedure to change the S2-LP's frequency after it has been initialized with a call to S2LP_RADIO_Init()?After I call S2LP_RADIO_SetFrequencyBase() the S2-LP appears to lock up. MC_STATE1 = 0x52 and MC_STATE0 = 0x29 which...
In the datasheet for the L6362A, section 11.8 mentions putting an external diode on OUTH or OUTL to protect against an open wire on VCC or Gnd. Looking at the block diagram of the chip, I don't see what the purpose of those diodes is. What am I mis...
There is a problem using SPSGRFC-868. let me write my steps,I generated 72Mhz/64 clock freq. for SPI SPI working mode 0 (Clck idle low/ first clck edge)(I tried 4 mode extra.)before loop SDN pin LOWBefore read-write Chipselect pin LOW, after that HI...
I am using Bluenrg-m2sp module and, I have flashed it from serial wire provision. I have used code provided in examples of "BlueNRG-1_2 DK 3.2.1" folder and program name is "BLE_Chat_Master_Slave". In SystemInit() function, code is waiting for the be...
I'm a not experienced student who has to deliver his thesis in a given time frame. I developed an Android app which has to send data as a client to a Nucleo-STM32F411RE server via Bluetooth. First I used the BLE expansion IDB05A1 where I have been ab...
