I am trying to develop some custom code using the BlueNRG-2 chip. I have my own custom board but first I am trying to get things to work on the STEVAL-BCN002V1 blue tile. That board comes preloaded with the Sensor Demo which worked fine. I am using t...
Hello,i need to know if you recommend to use the BALFLB-WL-08D3 at 433MHzI design my PCB with the STM32WL54CC, and it will operate between 433MHz and 435MHz. i want to know if the BALFLB-WL-08D3 is suitable for my application or if is better to desig...
I am working with BlueNRG 2, and Tile both... I'm working in BlueNRG-1_2 DK 3.2.3. In the xx\BlueNRG-1_2 DK 3.2.3\Firmware\BLE_Examples\BLE_SerialPort\BlueNRG-2 folder, there is Server bin and hex files which work great. However, when I go to the C:\...
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)...
