Why does BlueNRG-1 wake up once 10 seconds?

I used BlueNRG-1 to make 1 minutes wake-up timer. But it seems wake up once 10 seconds. It causes current consumption more about 1.5uA. How to solve it? Detail information is at attach file. My code snipped is as follows. #define SCAN_RESPONSE_TIMER ...

BlueNRG-M2 idle power consumption too high

I am building a non-connectable beacon using a BlueNRG-M2SP board, and an STM32L412 MCU as a host, and the power consumption of the M2SP board between advertisment phases is around 24 uA, which is over 10 times higher than what the datasheet says (2....

We have encountered difference in height dimension on ST1S10PHR. Per datasheet, height under "A" should be between 1.5mm - 1.7mm, but we have received parts at 1.47mm. Is this normal? is there a tolerance height range of +/-0.05mm to consider? Thanks!

STUSB4500: VBUS_EN_SNK seems redundant in certain applications.

We are using the STUSB4500 and we plan to use VBUS_EN_SNK in its default mode. This means that the whenever a source is attached, that power is passed on downstream. That begs the question: what's the point of using VBUS_EN_SNK and the FET it control...

BlueNRG gdbserver for ST-LINK V3

Hello all,I’m just getting started playing around with BlueNRG 1 & 2 devices. I’d like to be able to debug with an ST-LINK V3 not using uVision. I found a patched ST LINK gdbserver in the 3.2.1 DK download but it’s an old version that doesn’t seem ...

S2-LP getting into unknown state (MC_STATE0 is 0x29)

Greetings, I'm configuring the S2-LP to act as a receiver and then strobing the reception. Sometimes the reception works and the S2-LP goes to the RX state as seen from the first 2 bytes of status on MISO . Sometime, randomly, it goes into an unknown...

Hi everyone, does someone know an example of communication of CANOPEN and which evaluation kit iwith STM32 is possible to use it?

For my project, I would like to create a communication (CAN and CANOPEN) with an evaluation kit of ST and an other electronic card and a sniffer to analyse the different weft in the bus. But I'm a novice in this communication so I search an example o...

Hello, can you please provide reliability data (at least a FIT value) for the STPIC6D595MTR? A document would be nice. Best regards, Markus
