Hello,We are using S2-LP (the 826-958 MHz version S2-LPQTR) for application which uses 826 MHz as a base frequency."AN5528 Radio communication range estimation in ISM band" gives some results about the S2-LP range at 868 MHz base frequency.Could you ...
I have an IO-Link sensor and would like to interface it with my STM32F103 - Bluepill or STM32F407 - Discovery board, after research found STEVAL-IOD003V1 IO-Link transceiver and found it helpful for my application.1) I wanted to know if there is any ...
Hi, Can someone please help me explain what's going on or guide me in solving an issue with my STEVAL-IDB012V1 board? I'm debugging a project with WiSE Studio on the STEVAL-IDB012V1 board, but recently started having Launching problems with the devic...

Hello,I ordered this IC for one of my products and am confused about the SPI modes. In the datasheet, it is mentioned that it will support SPI mode 0 and mode 3, but I have not found any timing diagram of SPI mode 0 in the datasheet. Can you provide ...
I am writing to you as I am currently a computer engineering student, tasked with optimizing Bluetooth Low Energy for connected glasses. I tried to optimize the connection interval of the device, as the chip is a BlueNRG-M0. I am aware that it's not...
In my project I need to connect UART and I2C to BlueNRG-2 in module BlueNRG-M2. I need also to connect IO too.The inside module processor will manage functions.How I can program module processor? Can I use STM32CubeIDE?I also need to debug my code.
Hello community users!There is a question that needs to be asked. Any help would be greatly appreciated! We want to know Can S2_LP UHF module receive the differential correction data generated by our own gnss base station? So we'd like to know the su...
I use BlueNRG_Sleep() API to save power . But it wake up every 15s from WAKEUP_SLEEP_TIMER2 So how to close this
Hello,We're using mbedtls on stm32, and key generation for tls is slow. So, we've tried using a stsafe a110 for the key generation, and while looking on the i2c bus, we've seen that key generation from stsafe is about 900 ms.Is this intended ? is the...
I have a quick look, and find out that the Bluenrg-2 comes with 256 KB of flash and Bluenrg-1 comes with 160 kB of programming Flash memory.But what else? Can someone drop a quick summary or a link to an answer? Thanks.Andy
