Hello,I'm working on a schematic where an LVDS transmitter (DS90C385AMT_NOPB) connects to a display through a connector. In my design, a 100-ohm termination resistor is placed between the differential pairs TXOUT and RXIN, as shown in the second imag...
Hello all,I have a B-L475E-IOT01A2 Discovery Kit board and need to send 250kpbs rate of data from this board to a peer device using BLE.Is this baud rate feasible with this board?
Hello, We are looking to develop an efficient battery-powered device and I wanted to know the active and the standby power consumption figure at 1.8V for the ST4SI2M0020TPIFW eSIM module. There seems to be no mention of it in the datasheet but we nee...
Hello,For a project we need to simulate PSI5 sensors.We choose the ST L9663 but it can’t send PSI5 frame. It can only be used to send PSI5 sync pulse to sensor. It can only interface master to slave.I have searched on many website but I can't find a ...
I'm trying to perform a remote firmware update, with the bluenrg-lp ota service manager, I record the manager image at the base address 0x10040000 in sequence, i can perform the update without errors via ota, but when restarting the application, i ha...
Hi, I am trying to connect the STEVAL-BFA001V2B to a siemens ET-200SP IO-Link master. I have flashed the MCU with the STEVAL-BFA001V2_PredMaint_IOL_V1.1.0 using the STM32Cube Programmer. The PLC's IO link configurator connects with the BFA001V2B howe...
Hello all, I'm new to STM32 and I'm trying to setup a BLE sender test setup from Stractch using this video:https://www.youtube.com/watch?v=7f-55e2IR6MThe only difference is that I'm using BlueNRG_2 instead of BlueNRG_MS.I do everything according to t...
I purchased the parts of BD682 from Future. And I found the location of the packaging holes, some leaking copper, some exposed iron, and some plastic sealing, I am worried about affecting the corrosion resistance of the material.Could you help sugges...
Hello all, I'm trying to send 160 2-byte samples through the BLE platform each 10ms ( total bitrate of 256kbps ) to a single peer. I have been trying to modify the code for the HeartRate example project provided by the STM32 to achieve this rate.Howe...
I want to build a gateway that supports BLE and subGHZ frequencies (433 and 915MHz). Is it possible to use BLUENRG-M2SP and S2-LP, or do you have a better solution?What software I can use, STSW-BNRG-S2LP and X-CUBE-SUBG2 or anything else?
