Hello,I am using the BlueNRG 1 stack V2.5.0.I am using the callaci_gatt_add_char(SeviceHandle, UUID_TYPE_128, &char_uuid, 20, CHAR_PROP_READ | CHAR_PROP_NOTIFY, ATTR_PERMISSION_NONE, 0, 7, 1, &CharHandle);But I am seeing that I don't always see the ...
Hello,I want to connect a muxed PSRAM (ref: W956D6KBKX) with STM32L4S5VIT in LQFP100 package, The PSRAM requires IO signals at 1.8V. and in the MCU tension is fixed at 3.3V.So is it advisable to use level translators to convert the IO signals from 3....
I am using a BlueNRG-LP and started with the CCA01M1 I2S project. I changed the callback so that it applies a volume to the stream in real time. But this seems to block the code if I use a double (which id like to do to see some precision - and I wan...

Hello,I'm trying to connect SIM7000E with STM32L476VGT by using UART4 (PA0 as Tx and PA1 as Rx)I'm already using USART2 to show messages in RealTerm and I can't use the other UARTs because I can't find the pins on the board.This is the code I'm tryin...
Morning community, I'm currently working on connecting my STM32 F4 Discovery board to an HTTP server using the lwip stack, I manage to find a demo based on cubeMX on this internet site https://www.waveshare.com/wiki/File:Open407V-D-Demo-HAL.7z, so I...
Hello, I have configured a BlueNRG-M2SA as a network coprocessor using the provided DTM_SPI.hex file. I have connected it to an external uC and am able to read data from it. The problem is that as soon as the BlueNRG boots up and the interrupt is ena...
HelloI I've read datasheet of STA8090WG, but intead of clarity, many questions arose. First of all, is this chip come with preintalled firmware, or I shoud flash it by myself?Whether there is a reference circuit for this chip?Which interface I should...
Hi !I'm currently having problems uploading software to my STEVAL-IDB008V2 evaluation board having BlueNRG-232 on it. I'm using STM32 Cube IDE to edit my project code and BlueNRG-1_2 Flasher Utility to flash it on my board. Everything was working fin...
