Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I am working on a way to characterize how many capacitors one might need when using a microcontroller. I've seen an incredible variety, but I'm curious if there are any ways of determining by assessing number of power pins and I/O if a range or minim...
Hi everyone,On my custom board (STM32L442 + BlueNRG-MS), I am currently trying to get working the BlueNRG chip using the BlueNRG GUI software.I used CubeMX (V4.26) to implement the BLE middleware and to set up the interface between the MCU and the BL...
Hi, I'm new using ST devices so I don't know how to resolve this. I already saw some examples to send data from my computer to my board using ethernet, but I cannot find the opposite.I have a Nucleo-F429ZI and I want to send http query from my board...
I'm working with the STEVAL-IDB006V1 Board. I want to see the Bluetooth MAC address of "smartphones". I can see the MAC address of other BLE development boards, but I can't see the MAC addresses (or device name) of "smartphones" as a result of the sc...
Hello :)This USB-C is confusing me. According the standard you should be able to receive or to send power. I am using the STEVAL-ISC005V1 Eval board form ST. Unfortunately the PD2 and the PD3 line is not active if I plug the device into a Laptop.So m...
Environment: Usingng the SPBTLE-1S "postage stamp" on my own board [3v3 supply, external regulator from 12-400V, 100mA available], (using the programming/serial from a STM32F030 Nucleo board) and that works quite well (wish it supported more break...
my project is based on energy optimization of stm32f303. so for that how i supply different input voltage (because i use dynamic voltage scaling) and i how i measure the current value?
Posted on May 14, 2018 at 12:00Hi,I would like to know if watchdog can wake up BlueNRG-2 chip from deep sleep?Is watchdog powered and has active clock in this sleep mode?Kind regards,Piotr Romaniuk#bluenrg-2 #watchdog
Hello.I use the S2-LP DK_1.2.1 project example "SDK_Chat.c" as the base for two Steval-FKI433V2 PCBs.The 1st Steval with unchanged SDK_Chat.c program is used as a base device, connected to COM-port, the 2nd Steval without connection to COM-port shoul...
Hi,I'm facing a problem with TX Buffer in my Through Put test using two SPBTLE-RF module. One acts as Client, and one as a Server.The test is simple, continously call aci_gatt_write_without_response to send 20 bytes of data 1024 times (20 KB) and mea...
