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 ...
Hello, as part of a connected bracelet project intended for the medical surveillance of the wearer and alerted in case of emergency, we would like to know your on-board solutions allowing us a gsm connection in order to send data relating to the heal...
I've bought STM32F103 and St-Link/V2 and wanted to program and debug it via STM32CubeIde 1.7 . I connected the 2 devices and the laptop. I wrote a simple programand tried to debug: I got problems. St-Link needed an upgrade, but the Upgrade tool could...
Bluetooth development is a new field for me so I would like to start without any doubt.I'm checking the X-NUCLEO-BNRG2A1 for learning and using BLE in another project.My question is about the register mapping on the datasheet of this board. Why are...
Using a BlueNRG-LPI am wanting the advertising packet to show the battery level and some other changing data - pretty normal for a BLE device. So I have it advertising normally and I call this function every 10 seconds. This however seems to just sto...
