BlueNRG-2 timestamp registration

Hello,I would like to ask for an advice related to the timestamp registration:uint32_t timestamp_A = HAL_VTimerGetCurrentTime_sysT32();and after some time we check the elapsed time using:int32_t diff_ms = HAL_VTimerDiff_ms_sysT32(HAL_VTimerGetCurrent...

We are developing a circuit with the STuW81300. Our doubt is: to write a register, do you have to send 32 bits directly? or can you send 4 bytes, one by one? Thank you.

S2-LP to BALF-SPI2-01D3 connection 1mm Thickness 2 layer PCB.

The trace thickness and gap in the datasheet for connection from S2-LP to BALF-SPI2-01D3 are given according to a special 4 layer stackup. What should this trace thickness and gap be on this connection 1mm thick 2-layer PCB? Dielectric constant = 4.3...

Cannot calibrate antenna on ST25R3911B

I'm trying to issue the CALIBRATE_ANTENNA (0xd8) command on my st25r3911b nucleo expansion board, but it seems to hang.Other commands (eg. MEASURE_CAPACITANCE and CALIBRATECAPACTIVE_SENSOR) work just fine and generate interrupts, but issuing CALIBRAT...

SPSGRF-868 alternative

Hi, We recently saw that SPSGRF-868 (https://www.st.com/en/wireless-connectivity/spsgrf.html) has become Not Recommended for New Designs (NRND), which seems concerning as we use it in many IoT designs.Is there any ST module available, with ACTIVE sta...
