Hi All,In the reference manual for the BlueNRG-LP Cortex M0+ microcontroller (RM0479), it states both page and mass erase functionality for the flash controller. But, only one "ERASE" command is given (0x11), which appears to be for page erase.Does a...
Hello All,I am new to Bluetooth and would like to use the BlueNRG M2 as a hosted network co-processor. I am reading the Bluetooth LE primer from the Bluetooth SIG. Could someone please point me in the direction of some resources that allow me to use ...
Hi.We are trying to measure analog values using BlueNRG-2.We want to calculate the accuracy, but we can't find any description of accuracy or drift for Vref (0.6V) or adc in the datasheet.Are there any reference materials or data available somewhere?...
Hi ST Community,I use the X-CUBE-BLE1 library and the SensorApp application, and I can understand most of the functions used, but when I want to add a value to my characteristic, I can't understand the address used and why.The address of the "environ...
Dear community, I'm using steval idb008v2. I'm trying to debug it with stlinkv2. Is it possible to do it or not? Do I have to move some pins or something similar? The application replies me that so stm32 board is not connected. Any suggestions please...
I'm developing a power line communication with the ST7580. Sometimes I get an error code 0x08 returned by ST7580_DlData function. This code is not listed in Table 14 of the user manual. What causes this error?
Hi, We are using ST3485EIDT and ST3485EBDR RS485 IC in our Gateway device to collect the data from Slave devices. We are reading 30 parameters (1 Packet) from slave Device. Frequency: 1 parameter per sec. Baud Rate 9600 bps. We are noticing some issu...
Hello, i am really new to pcb design, in fact this is the first time i done it. the problem i get is, where to do i connect the BOOT0 pin? i know if you connect it to VDD then it will boot from the system memory. if i connect it to gnd then it will b...
I am programming stm32411CeU Blackpill- i want to make connection between the Stm32 and Pc Via RS485 ..i wrote this simple code like in the photo..but i have problem with the output .. i get this weird characters like in the photo i tried different n...
Hi, I'm new with this development board.My target is to use the S2-LP DK Application to configure the board to send data from a GPIO.Do I have to put my data on GPIO_0 and the clock signal to GPIO_1?Why is the clock signal needed?In this way it is po...
