BlueNRG-2 SoC + hci_le_encrypt() output
Hello,I'm currently working with the BlueNRG-2 SoC. I would like to add AES-128 encryption at application-level while leveraging hardware acceleration.The only function I've found that seems to do the job is hci_le_encrypt(). Based on the documentati...
Try to connect STM32 SigFox Discovery Kit B-L072Z
I have already tested this devkit on LoraWan Network (Objenious) and it works perfectly with Lora Expansion Cube IDE. Now I try to connect it with the SigFox Cube IDE extension but when I press the button, it sends data (read on COM port) but cannot ...
Stm32Nucleo F446Re and xnucleo gns1a1 doesn't communicate
Hello everyone,I'm actually trying to make a datalogger for a xnucleo gnss1a1.The expansion board is connected with a stm32f446re Following the manual about the connection between the two boards ( referred to stm32F401RE), I've set all the pinou...
Interfacing HX711 load cell amp using STM32F407VG
I am trying to receive data from the HX711 amp. This module requires a CLK signal from the mcu (stm32407VG). What is the best solution to send a clock signal to the HX711 module from a GPIO pin ? How to configure this GPIO pin in CubeMx ?
Resolved! Lora node ns1 AT master
Hi everyone, I have a p-nucleo lorawan 3 kit with a nucleo-l073rz board and a lorawan ns1 lora board. I'm trying to setup the AT master example from I-NUCLEO-LRWAN addon using keil uvision. I uploaded the program and activated the CMD_DEBUG but I do...
S2-LP SDO pin not tri-stated issue fixed?
Hello,The S2-LP errata sheet dated 11//2016 states that the SDO pin does not tri-state as expected, for silicon with device info 0x0391.Has this been fixed in later silicon revision?Please advise. Thank you.Regards.
Custom board with SPBTLE-RF0 module using the X-CUBE_BLE1 software package initialises and advertises to mobile phones but connecting to device fails with Error 133 (0x85): GATT ERROR?
Hi,We are currently working on a custom board with the SPBTLE-RF0 used for BLE communication and a uC from the L4 family (STM32L4A6VGT6P). We used the SensorDemoBLE example as a starting point and programmed it to the board through SWD. From adding b...
I2C with Melexis 90640
