Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
We are using BLUENRG-232 in one of our low cost designs. On page 138 of the datasheet, we can see two DC-DC converter configs. For cost savings, we would like to go with non-active DC-DC converter config. However, there isn't much info available abou...
My project involves using two SPSGRF-915 RF Transceivers (one acting as a transmitter while the other as a receiver all the time). I observe some degree of packet loss using a debugger window connected to the receiver node, and a Logic Analyzer conne...
I'm looking at designing the SPIRIT1 into a new design.The datasheet suggests up to 500 kbps (over the air), is this true for all bands, i.e. will I see 500 kbps at 169 MHz? This would make it much more appealing.
I'm trying to connect to a sensortile.box via bluetooth with BlueSTSDK in python. When I want to get list of devices i got following error:TypeError: Can't instantiate abstract class BlueSTAdvertisingData with abstract method is_device_sleeping I go...
Hi all I am using the BLUENRG-M2SP ble chip set , i created the 2 services ,there services are Primary Services 1. first service has the 3 characteristics and Second services has the 5 characteristics , if i add third services , i am getting Lack of ...
Hello,We are currently working on a USB type C based fast charging system design and interfacing STUSB4500 with MSP430G2553 to compliant PD for fast charging. We are successfully able to read and write registers through I2C.So Is it require to implem...
Hello guys, I am a new B and have started the cours of leaning coding and CubeMX, but I would really use some of your enlightenment!I've been playing around with a couple of 3D printer boards using Marlin Firmware to drive my Pick and Place Machine f...
Hey everybody. I am new to RF modules and was wondering if you need an antenna for the SPSGRFGC-868 RF module to work. I am working on a vagus nerve stimulation system for my university. Long story short, the VNS system has an implanted pulse generat...
Hello everybody !I am working on a project with a STM32F746ZET. The embedeed system measures temperatures, currents, voltages, save it on EEPROM, and send Altert with Ethernet/Can when there is a problem.Now we would like to add the possibility to ch...
