Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Hello,I am currently working on a project that requires 6loWPAN over Bluetooth communication. I have a STEVAL-STWINKT1B development board and it comes with a BlueNRG-M2 BLE module. I have checked the BLE examples and the documentation provided by ST,...
I have configured the GPIO for I2C1(Alternate function 4) and enabled the Clock for I2C1. After that I am trying to enable the ACK. but not able to enable that.. Also tried for I2C2 and I2C3 facing the same issue.//enable the clock for the I2C periph...
What are the power levels for the different settings when calling aci_hal_set_tx_power_level()? All I can find for sure is a max power level of +8 dBm in the datasheet. Other tables I find in the BlueNRG-1_2 DK documentation give conflicting answer...
Hi, I'm looking for the code source of P-NUCLEO-LRWAN3 Gateway, the user manual only have the .bin file.
My project involves a Nucleo-64+X-NUCLEO-BNRG2A1 communicating with an Android phone via Bluetooth.I successfully sent data from the server (BNRG2A1) to the client (Android phone), but I cannot figure out how to do the same from client to server. Und...
I have a simple project I am trying to implement using BLUENRG2-M2SA. It will connect with a user over BT and download a timer length. Then it will run the timer and blink lights when the timer counts to zero. The user then acknowledges the lights...
Hello,I'm developing a board with the BlueNRG-M2 module. I'm also using an ST-LINK V3 with uVision to debug/program. I'm also using the VCP made available by the ST-LINK V3 for some good old fashioned printf telemetry. The VCP is connected through...
Trying to build a 433 MHz sniffer based on SDK example "SDK_Sniff_B.c". Im sniffing messages from TPMS sensor and get them on my PC with RTL-SDR. In the message parsed on PC I can read ID of sensor which goes right after sync word. With the help of U...
I want to use hyperflash (S26KS512 or S26KL512) with stm32h723zet6 microcontroller.The memory has "Phase Shifted Clock" pins.What should I do with them? Connect to GND or VCC or Not Connected?Hyperbus interface (stm32) support 1.8v?
My main problem is to reduce the power consumption of the HC-05 Bluetooth module. As it may be known, such a module consumes lower and lower energy when it is in the AT Command Mode (between 1.5 and 3 mA current). Since my project requires sending re...
