Ble Receiving Junk data

hi all i am using blenrg2 m2sp chip as network mode. its operating as peripheral device and communicating with host controller through UART with 115200 baud rate .I received BLE read characteristic request , i did not response till 1 second ...

S2-LPTX module different supply levels for analog/SMPS and digital

Hi!I am designing my own sigfox board using S2LPTX module, some sensors and a ST microcontroller. Microcontroller and sensors are working on 1.8 V supply. I know that S2LPTX module can work with VBAT = 1.8 V, but in section 3.2 it mentions VBAT shoul...

Hello, I have problem with connection between JLINK and custom board with BLUENRG_LP chip.

I have BLUENRG-LP chip on my custom board and I'd like to flash beacon example inside. The example is one from BlueNRG-LP-DK-1.0.0 named BLE_Beacon.As the debugger I try to use JLINK (tried CMSIS-DAP configuration as well) but I'm not successful.This...

TESEO LIV3F - update rate says 10Hz, does that mean it is updating location based on satellite data at 10Hz? Or is it using interpolated data ? Does this module have an integrated IMU?

S2-LP (and its GUI) problems

Hi!I have S2-LP connected to S2-LP GUI (only difference - it has no EEPROM on board, so I recompiled CLI firmware with EEPROM_NO define, and it has quartz running at 25MHz). I have to receive packets with 30-50kpbs datarate, but I made slower packets...

How to read data from pins? STM32F4

Hello everyone, I would like to know how to read data from pin on STM32F4. I have a small project where I am blinking led (it's running throw Arduino board) and I would like to see throw STM32F4 when it's on and when it isn't. How should I setup pin?...

STM32CubeProgrammer and ST-LinkvX {any version} stopped working...

Sorry, but this is not really a question as much as some interesting information.Until yesterday all of my ST applications were working perfectly on a Debian v10.9 installation. Then I started getting this message....../STM32_Programmer_CLI: symbol l...

I am using "54VCXH163245" bidirectional level shifter in one of my ongoing projects. I am using VCCA as 3.3V and VCCB as 1.8V. My queries are: 1. Is there any power-on sequencing requirement for 1.8V and 3.3V for this device.?

However, For similar level translator device like "54AC164245", there is an explicit requirement of sequencing of 3.3V and 5.0V . Please confirm and clarify.Then datasheet of device "54VCXH163245" says VCCA must be higher or equal to VCCB, but for "...

Make S2-LP talk to nRF905

Hello,I have a need to make the S2-LP communicate to an existing RF system which is based on the nRF905. From the reading I have done it looks like it should be possible. Does anyone have any suggestions on how to configure the S2-LP to do the job?Th...
