What's the purpose of R12 and C12 in the circuit? I have come across another circuit which R10 is 10K ohms and R11 is 2.2K ohms without R12 and C12 connection. I'm having some issue when powering up a board design with R10 (10K ohms), R11 (2.2k ohms)...
I'm developing a very simple product using BLUENRG-232N. I was wondering, whether this device can function as an SPI master to just read some data from sensors, and send it over BLE ?The documentation is also pretty confusing. It says that there are...
Hi,I just got a STEVAL-IDB008v2 boards and I want to test lighting demo example available in STSW-BNRG-Mesh. I have followed the steps in "Getting started with the ST BlueNRG-Mesh embedded firmware". Unfortunately, there is error while building the p...
I want to use the BNRG-MS2P of this module with an Arduino. More specific with a custom PCB with an atmega328p. Any tutorial, Literature I can use. This is a new field for me
Hi,I have a project that needs BLE connection. Right now I have a custom PCB working with a premade BLE module (SH-HC-08), the PCB has an atmega328p. Now is the time to upgrade with a custom BLE chip for creating my own characteristics.For this, I st...
My device init looks like this: ret = aci_gap_init(GAP_PERIPHERAL_ROLE, 0,0x08, &service_handle, &dev_name_char_handle, &appearance_char_handle); if(ret != BLE_STATUS_SUCCESS) { //PRINTF("GAP_Init failed: 0x%02x\n", ret); return ret; } r...
So I'm new to the stm32 line up and I'm currently trying out the STCUBEMX code generator. After generating the code, I can't seem to find the configurations for the pins I selected. For example, I chose PD5 and PD6 as TX and RX for USART2. But when I...
I'm designing a guitar pedal using my F767ZI Nucleo, and I have an input stage current buffer using a TL072 op amp. I'm using the Nucleo's 3.3v as VCC.I would like to know if I can wire the op amp output pin directly to the ADC pin on the Nucleo, or ...
