Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I am a bit confused about the number of connections the BlueNRG-LP can handle.The device is advertised with 128 concurrent links.I visited a ST talk where the discussed number was about 50 Connections.I used the BlueNRG-LP 1.0.0 Radio Wizard that lim...
At the moment with the X-NUCLEO-PLM01A1 + Nucleo-F401RE boards is supplied a firmware stack with only PHY and DATA link.What full stack do you suggest to use with ST7580?An old job of Nunzio Dipaola (Application Note AN4411) build a 802.15.4 stack ov...
Recommendet is 66µm CU with 305µm distance to ground layer. I would like to have 35µm CU with 180µC distance to ground layer.
I am using a BlueNRG-LP MC355 SoC. When connected to my debugger, I can call NVIC_SystemReset() just fine. However, if I disconnect the debugger, the device hard faults on reset.uint8_t ret = BLE_STATUS_SUCCESS; uint16_t service_handle, dev_name_...
Hi everyone,I try to implement the stack Bluetooth 4.2.0 X-CUBE-BLE1 with the sensorDemo application on a Nucleo-L452RE evaluation kit, coupled with X-NUCLEO-IDB05A1 Bluetooth Board.The code C has been generated thanks to STM32CubeMX 5.0.0 standalone...
Please help me with the setup required to flash the latest firmware version for the BlueNRG devices. I would request your help to explain me the setup required for both the usecases exlained below -There are some devices we have in stock and they nee...
Hello,I'm using a STPM32 to measure the ac line voltage and current. It is connected via a galvanic isolator ISO7341CDW to a STM32F072 with SPI. Most of the time, this works just fine. I can read the correct RMS values for I1 and V1 (Register DSP_REG...
Protocol Used : SPISPI Master : ESP32SPI Slave : STPM32 I am trying to interface with STPM32 using SPI interface.Whenever I make any read request I am getting the value of 0x00 register again and again which is 0x040000A0.As per the datasheet the int...
Hello,we purchased two ST4SIM-200M eSIMs for testing but we have trouble activating them. In the truphone portal when I enter their ICCIDs, I always receive "This ICCID has already been activated". They should not be activated, they are brand new not...
