Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Using an Aukey PA-Y10 supply with the STUSB4500 works fine for all the five fixed-voltage PDOs (5V, 9V, 12V, 15V and 20V).However, the supply's manual says that it features a PPS output with 3 to 16V but I found no way to access this with the STUSB45...
I use SDK_Chat example (S2LP DK1.2.1\..\S2LPLibrary_Examples) as a base for my project.To increase a Communication range I change next parameters:DATARATE 38400 (default) to 4800POWER_DBM 12 (default) to 14RSSI T...
I am using an M41T62 to test the various repeat modes using bits RPT1-RPT5. Most of the repeat modes appear to be triggering an alarm properly, with the exception of MONTH (only RPT5 set) and YEAR (RPT1-RPT5 clear).For example, to test this, I set t...
Hi all,I recovered 2 old ST7540 DEMOKITs complete of the related ST7-based COMMBOARDs (photo attached); however I don't have the DEMOKIT GUI that is cited in the UM0239 I found on the ST website (https://www.st.com/en/interfaces-and-transceivers/st75...
The LEDs labeled Sensor 1, Sensor 2, Sensor 3, and Sensor 4 are all flashing on my board even though I have the STEVAL-IDP005V1 connected to an IO link port.Are the lights supposed to keep blinking when I connect a sensor or do the blinking lights me...
Hi,I'm designing a beacon around the BlueNRG-2 and would like to power it from a battery that can output as much as 3.67V. Unfortunately this exceeds the max Vin limit on the datasheet (3.6V) by only 70mV. I have a couple of questions in the hopes of...
Is there any plastic box for STEVAL-BCN002V1B board. And what is maximum data size which we can sent via bluenrg-2 when BLE characteristic is configured as notify?Thank you in advance, Nikola
I am using NRG-1 for my product development but I have only NRG-2 kit on hand. I am using NRG-2 project to develop my SW for using DK kit but I found there are 250kHz frequency offset when the software is applied to my HW for using NRG-1 inside. Is...
Hi all,I am working on NRG-132 for my product development and it is fine for spectrum with Power Level from 0 - 14 (ie -18dBm -- 4dBm). However, when I set to powerlevel = 15 or PA_level in BlueNRG GUI in level 7, the output spectrum will be distort...
