Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Hi, I am using Nucleo-F401RE board, X-NUCLEO-S2868A1 expansion with S2LP and X-CUBE-SUBG1 software. Using code from udp sender and receiver examples, modified to each node be able to send 6LoWPAN message to other node, and answer to message back. Whe...
Hi, I'm SaeedRecently I designed my own PCB for Bluenrg IC for my project. It's OK when I want to connect to it and send data in small length i.e. 10 Bytes per second.But when i want to send data in 48Kbps, it disconnects from my cell phone when only...
What is the use of TEST pin on BlueNRG-1? STEVAL-IDB007 has a 100K pull-down connected to it, with a jumper that allows a connection to VDD. BlueNRG-MS has it connected directly to GND.Datasheet states that it should be connected to GND, so I expect ...
Dear members, reading iO-Link transceiver datasheets like for the L6362A i wonder why the Q/C pin and the DI/DO pin are capable of driving loads, i.e. like inductive loads? As far as i understand these pins always are connected to the master, never ...
I have two KSZ8851SNL connected to an STM32H7 board.In a certain operating mode, I would like to make a 'transparent' connection (on link level) between the two interfaces, so the board with the two interfaces acts like a simple hub.So if I receive a...
Hello everyone. I'm working with the S2LP transceiver and the 802.15.4g packet format. I'm using the SDK coming with the x-cube-subg1 (https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/s...
Hello There,This a question for those who know Firmware and Hardware well.Currently I am working IAR 7.80.2 1 months trial version.I need some help.Currently I am trying to download firmare of WIFI module through a USB serial COM port.I have SDK firm...
Hi,I run the "LwIP_HTTP_Server_Netconn_RTOS" example well on STM32746G-Discovery board. I can see webpage after type "192.168.11.1" in browser.I modified the gpio configuration in "HAL_ETH_MspInit"I modified the HSE_VALUE from 25M to 8M (my board use...
Dear communityWith interest I read the following thread on the topic:https://community.st.com/s/question/0D50X00009XkffySAB/spirit1-missing-irqI probably have a similar issue. My application seems to "lose" RX data sporadically. There may be a relati...
hello,i work with the IDS014A4 SPIRIT1 WMbus board,i like to send a frame with the C1 mode(unidirectionel Sent).my first question is : why the Tx frame preparation is limited with12 bytes ?my programme can not sendall the data only when i replace :S...
