Also I am trying to use dio9 which has internal pull up ..for triggering the interrupt it seems to not detect both rising and falling edge in this case Can u please help ​

how to use demo codes

I'm very first time using bluenrg1. I saw a lot of sample codes. In my project I have to use two i2c one is to receive data other is to display data.also I want to send the data through bluetooth. For these cases which demo code is suitable. please h...

Is it possible to set the agc to a fix value ?

Hi,I have a question about the BlueNRG2 device: is it possible to set the agc (automatic gain control) to a fix value ? Maybe in the RADIO_CONFIG register ? But there is no info about the content of this register !Thanks a lot !

Hi All, I'm using Bluenrg in one of my project. The pins selected for debugging is SWD pins.Is it possible to use these SWD pins as debug pins in the time of debugging/programming and as GPIO pin in the rest of the code ?

How to connect with the BlueNRG-M2SP module?

I wonder how to connect the pins of this module as it has a very form factor.For example, it has an expansion board?

Hi, I accidentally deleted the firmware in STM32L151 MCU. (I used connector CN6 instead of CN7.) STM32L151 work as a converter USB/UART. Because it is not detected, can not update firmwar STM32L151. Where can I get a hex or bin file for MCU STM32F151?

Thank you for the tip. Jiri
