Hello all!I have a STEVAL-STWINKT1 board and I have created my custom services and characteristics to be able to send to a Raspberry Pi an uint8_t array of 240 bytes.From the RPi side, I am using bluepy to connect to my board and receive the notifica...
Hi there,I'm running into some weird problems while trying to use the S2-LP transceiver. It seems as though the transceiver is only sending one byte each time it enters TX mode.I am writing a program for a heavily storage-constrained project and as s...
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 ...
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 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...
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 ...
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...
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...
