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...
Hi,Can someone explain to me how I can remap the vector table after jumping from a bootloader (stored at 0x10040000) to my user application (stored at 0x10040800) ? I know the cortex M0 has no VTOR register, but I found no documentation on where I sh...
Also I am trying to use dio9 which has internal pull up ..for triggering the interrupt it seems to not detect both rising and falling edge in this case Can u please help
I'm very first time using bluenrg1. I saw a lot of sample codes. In my project I have to use two i2c one is to receive data other is to display data.also I want to send the data through bluetooth. For these cases which demo code is suitable. please h...
Hi,I have a question about the BlueNRG2 device: is it possible to set the agc (automatic gain control) to a fix value ? Maybe in the RADIO_CONFIG register ? But there is no info about the content of this register !Thanks a lot !
Hello,I would like to develop a sniffer using BlueNRG-2 chip. Each system will be able to transmit packets with an unique ID and to receive packets from the other devices nearby (also devices based using BlueNRG-2). The aim is that all the devices sh...
