Interface and connectivity ICs

i cant read and send data between UART2 of a STM32L476rc (PA2 and PA3) and the BlueNRG-2N UART(DIO8 and DIO11), i want to read the hw and fw version of the blueNRG .

I designed a PCB with an STM32L476rc and a BlueNRG-2N, the buenrg is conected with usart3 and i want to read the bluenrg version and send it to usart2 to show it with docklight please can someone give me a hand in the source code ,

BLE performance of BlueNRG-2N

Hello everyone, I am designing a custom board (STM32L476 MCU paired with BLE connectivity, among other components) and after search decided to use BlueNRG-2N module along with Antenova A5839 Antenna.Tried to follow AN4819, despite the tight PCB space...

What are the effects of clock drift in a multi-master setup?

I have three devices. D1 is Master of D2 and Slave of D3. D1 is Master and Slave at the same time. D1 must receive a packet from D3 at the anchor point, and must send a packet to D2 at another anchor point. Because of clock drift, I would expect thes...

Why i cant read and send data between UART2 of a STM32L412RBT6 (PA2 and PA3) and the BlueNRG-M2SP UART(DIO8 and DIO11)

I designed a PCB with an STM32L412RBT6 and a BlueNRG-M2SP, and I checked the connection and I can't read data from the bluetooth module and I can't send data from the STM32.I made the following code:stm32l4xx_it.cvoid USART2_IRQHandler(void) { /* U...
