Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Hello,I'm trying to find an example project where audio was streamed using the S2LP chipset, but I can only find Sigfox/LORA examples.Do you know of any off the shelf medium speed / real-time example using the S2LP IC? Our speed requirement is aroun...
How can I know if my IC is TDA7293 or TDA7293V?
I have a product in which a STM32F417 (BGA) micro is attached to a LAN8720A (QFN) Phy using the RMII interface. It uses an external 50MHz oscillator going to the Phy and STM32.For testing newly assembled PCBs in mass production, is there a way to tes...
Hi,When editing the GATT characteristic in the provided software for the SensorTile, I cannot increase the size of the payload being transmitted. Even after altering the charValueLen variable, this doesn't appear to affect the length of the packet be...
Hello,I am using the BLUENRG-M2SA in my design. In the BLUENRG-M2 datasheet at https://www.st.com/resource/en/datasheet/bluenrg-m2.pdf, it is stated that all GND pins must be grounded. However, in the BLE module integration design guidelines (DT0142)...
Hello,I really like the NUCLEO-WL55JC platform as it provides many features for FSK which I am using, but when I checked the UM, I didn't find a way to wake Up the MCU by receiving a Frame. From my experience, there should be a mode different than RX...
Hello,is it possible to enable/disable the "readout protection via SWD/JTAG mode for BlueNRG devices? Is it possible with openocd?BR Sebastian
Hello, I've been using the STEVAL-IDB008V1M to help develop an BLUENRG-M2 product for an company. I've noticed in the schematic there are 3pF capacitors connected to the ADC Input 1 and Input 2Does anyone know why this is done?For the time being I ha...
Our total Flash is divided between Boot Loader and application, and their linker scripts will look like below:Boot Loader memory sections are:Application memory sections are:Boot Loader starts at 0x08000000.The application starts at 0x0804C000.I'm ab...
I am using BlueNRG M2 in a network co-processor mode and want to send 10 packets per second, each of 100 bytes. I have generated code through STM32CubeMX and changed the ATT_MTU value from 23 to 247 in the bluenrg1_gatt_server.h file, which was gener...
