Hi,I have two GPIO pins on BlueNRG-LP connected to the reset and CS on a potentiostat device. The reset and CS need to be kept high during BlueNRG-LP deep sleep mode. Just wondering how to keep these two pins active while the BlueNRG-LP is put into d...
What pins should we use if we would like to interface with the BlueNRG-M2SA module via UART. We currently use a UART interface on an older competing Bluetooth module and would like stay with that communication interface instead of SPI which is used o...
Hey, I am a new user at this forum sorry for any lack in communication.I have an IO-Link sensor and would like to interface it with Arduino uno and after research found STEVAL-IOD003V1 IO-Link transceiver and found it helpful for my application I wan...
Hi,Thanks for your help in advance.I have a custom Linux board with a lsm6dsl module on the platform. The driver has been ported and I can read the Accelerometer and Gyro raw data from the Linux usersapce sysfs file entries. an interrupt line from th...
Hi all,does someone know where can I find a reference design for an external antenna? I would like to connect it via the u.fl connector to the CR95HF. I have found a tool ST25R Antenna Matching Tool. Can I use the same tool for CR95HF? If so what sho...
Hello st community,I'm trying to use the BlueNRG-355 in deepstop mode with timer, to wake it up with an I/O. I used function from Power Save Modes project from the Navigator with Bluetooth function. while(1){ ModulesTick(); APP_Tick(); HAL_PWR_MNG...
Hello everyone,I am currently having trouble making a simple UART communication (+ the HCI command-based protocol) between the X-NUCLEO-BNRG2A1 shield embedding a BlueNRG-M2 (which itself embeds a BlueNRG-2) and my Nucleo-G070RB. I cannot use SPI for...
Hi all,I've a project on STM32CUBEMX and STM32CUBEIDE and I'm going to use the STEVAL-STLKT01V1(https://www.st.com/en/evaluation-tools/steval-stlkt01v1.html ) so I'll have to decide what to choose between X-CUBE-BLE1 or X-CUBE-BLEMGR.Does anyone have...
Paired the BNRG2A1 module with the STM32L476RG as recommended in the sample application. But when debugging I realised that the hciReadPktRxQueue is always empty leading to timeout. I have made no modification to the sample application and even with ...
Hello Team,I am currently working with B-L475E-IOT01A2 for driving a "Waveshare" board "e-Paper IT8951 Driver HAT (B)" for updating E paper display. I am using SPI protocol for the same. I am trying to update the image but only 25% of the board is ge...
