Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I have initialized I2C on BlueNRG-248 as a master, and it is able to successfully transmit address and data to the slave, but is unable to receive data and acknowledgement from it. I monitored the lines on an oscilloscope, and confirmed that the slav...
Posted on August 10, 2015 at 13:32I am performing some tests on the CSMA feature. Specifically on the non persistent CCA method. I have a test process whereby every 10s the transmitting module has its TX FIFO flushed, has its FIFO filled with 20 byt...
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...
