Resolved! How to setup WiSE to build project for IDB011V2
Hi,first I install the BLENRG_LP Navigator, it generates lots of examples,then I use WiSE studio and open the hello world example, the default ld file is BlueNRG_LPS, but I´m using IDB011V2, which has the SoC BlueNRG_LP chip, then I tried change the ...
Enabling OOK in S2LP
Hello I have a confusion when the OOK is enabled in the S2LP chip.In datasheet section 5.4.2 writes:The ASK selection depends on power ramping enable.When OOK is selected, a bit '1' is transmitted with a programmed power, set by register PA_POWER[PA_...
STUSB4500 drives I2C SDA low during power up/down
I'm finding that t STUSB4500 drives its I2C SDA line low (for around 1 second) during power up or power down (the device is powered from Vbus only).This prevents all communication with other devices on the I2C bus during this time.Holding STUSB in it...
Resolved! ST3485 Communication
Hello Team,We have one project where we customer used the ST3485EIDT IC for RS485 communication.By looking the schematic design we see that DI pin is connected with UART Tx pin but its series resistor has been removed.We checked the functaonlity and ...
I'm having problems with the simultaneous central/peripheral connections. Can someone help me understand the timing constraints?
I am developing a prototype using a L4 stm32 microcontroller with a bluenrg m2sa BLE module which acts as central/peripherial. Also small sensors nodes with L1 annd the bluenrg m2sa modules. I'm having problems with the simultaneous central/periphera...
Resolved! BLUENRG-355MC debugging on WISE-Studio using PE micro debugger.
I want to debug my custom board based on BLUENRG-355MC using PE micro debugger on WiSE-Studio IDE by ST.1) Does WiSE-Studio IDE supports PE-micro debugger?2) In case it supports, how to choose PE-micro debugger in WISE-Studio IDE?3) In case it doesn'...
ST4SIM-200M Interfacing with local MNO
Hello, we want to use ST4SIM-200M eSIM IC. Do the ICs you sent come with the bootstrap profile installed? If so, how can we transmit the profile information you uploaded to local MNOs? It would be very useful to talk to someone from your Turkey Suppo...
Audio transmission
I have a STWIN SensorTile Wireless Industrial Node development kit ( STEVAL-STWINKT1B). I installed this code (https://github.com/STMicroelectronics/fp-sns-datalog1/tree/main/Projects/STM32L4R9ZI-STWIN/Applications/HSDatalog) to the board. STWINKT1B ...
How can I have iBeacon UUID ?
Hi,I use STM32L476RG and X_NUCLEO_IDB05A1 to find Bluetooth beacons and their RSSI.I try to use aci_gap_start_observation_procedure() and EVT_LE_ADVERTISING_REPORT to extract UUID, major and minor from an emulated iBeacon but there is only the MAC ad...
