Hi,I am a new to STEVAL-IDB011V1 board, so I installed the SDK mentionned on the user manual, However I couldn't found the package for this device on Keil µ-vision to start programming it!I search STBlueNRG-LP_DFP.2.0.0.pack on device database and i ...

St ble NRG2 (BLUENRG-M2SP) : reading the characteristic issue : hi Every one i using BLUENRG-M2SP chip , i using st ble sensor app to communicate the chip , the problem statement , AS below

1. if i read and write  characteristic in the service  its working fine if write one characteristic and read on other characteristic of same service , its not working . after that its not able to reconnect , during this scenario i need to restart ...

Hi, I'm interfacing Nucleo-L476RG with a UART Device. If I power off that devices, my Nucleo code freeze and I need to manually reset it. I need to power-on and to power-off the device and the Nucleo must continue to works.

Nucleo send through UART4 and receive with DMA from devices. Then Nucleo send to PC via USART2 for debugging. In UART4 there is Idle Line detect for receiving unknown length of data.This is my code: MX_GPIO_Init(); MX_DMA_Init(); MX_UART4_In...

X-NUCLEO-BNRG2A1 range is less than 10M on highest power level

Hi,I am experimenting X-NUCLEO-BNRG2A1 board and I have found the range is not as I hoped (about 5 Meters without any barrier).I have set the power to 1,7 which I believe the highest power level +8dbm.Is there any way to extend the range?Does using e...
