Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
The ST60A3H1 looks very interesting. While I understand an NDA is required for access to the complete details on this solution, would it be possible to say if it works underwater as communication between ROV modules?Scenario:IC A | 1mm air or mineral...
Good morning everyone, I am new to the field and would like some advice on using your sensors. I am trying to create a script in javascript (I am using noble.js) in order to connect a number N of steval bcn002v1b sensors with bluetooth connection and...
Hi!I have a problem with reading data from MPU-6500 gyroscope/accelerometer (Arduino-module GY-6500/GY-9250). I am using the I2C protocol. When reading the WHO_AM_I_REG register ( with address = 0x75 ) I always get the number 0x70, although all publi...
Hi everyone!I'm trying to integrate my own touch controller with TouchGFX on a custom board. My touch driver gives me XY coordinates of an event (press or release). Basically with this information I can do whaterver I want. So, for example, I can cha...
Hi All,I am currently using your RTC: M41T81M6F and I am evaluating to add, as additional homologation, your RTC: M41T81SM6F.I have seen that the “new” one has additional features such as oscillator Fail detection and Battery Low detection, however o...
hidoes anybody nows how the auto fequency offset works?is there a register? it works only with the steval board ?how does the board calculate the correction?Thank'smarco
Hi everyone,I am currently designing my own PCB board using the bluenrg-332ac chip. I want to use the ufl/SMA port to connect my antenna without connecting the PCB antenna. So I wonder how to remove the PCB antenna from the PCB layout with only UFL p...
Hello,The STUSB1600A has a standby power mode that is described in the datasheet as being disabled by default, and can only being enabled through NVM reprogramming.However, when using the STUSB GUI (v. 3.2.3) connected to a STUSB1600A and NUCLEO-F072...
I use BLENRG-MS and stm32l07 mcu. Mcu call the APIs to control the BLENRG-MS module. MCU initialize the ble module and start observer process by calling API,and the process will be terminated in three seconds. The problem is that program may trap in...
I'm using Bluenrg-M2SA with and facing issue with ble connection. Bluenrg-M2SA is connecting as a client with smart watch but it gets disconnected at every 30 seconds. Error: hci_disconnection_complete_event, Reason: 13I'm using BlueNRG-1_2 DK 3.2...
