Hello all,I have an issue when I compile the exported C code from the BlueNRG GUI. I have the STM32L152RE nucleo board with the IDB-05A1 expansion board. My exact issue is that although everything works fine when I’m using the GUI, when I export the ...
Posted on October 29, 2015 at 13:26Hi all,I have a BlueNRG-MS-based GATT server with several characteristics, and I'm able to read and write these characteristics from Android. Now I need to implement a GATT client using BlueNRG-MS to access the GAT...
Posted on July 14, 2018 at 02:19Hello! I'm having problems with using USB comm ports and STM32. I've used CubeMX to configure the USB as a CDC. When I first upload the firmware to the micro it works well on windows 10, but as soon as I reset the boa...
I would like to change the names of my devices (at the device), and it looks like the BTLE spec says that Write access is "Optional" https://bit.ly/2NYnkvoIs it better to do that (and how would you do that, since it's in the aci_gap_init function and...
Good day, Support Team,I have a question regarding BlueNRG-1 simultaneous master/slave mode support.As I see from documentation "BlueNRG-1, BlueNRG-2 BLE stack programming guidelines.pdf" - BlueNRG-1 can support master/slave mode to be connected to t...
Hello,I am trying to read attribute from connected slave device on my BLE master device.Both devices are BlueNRG-1, the first device is configured as slave, the second device is configured as master/slave.In master mode I try this code to read attrib...
We are developing low power BLE device , for smart watch ,we need example codes for BlueNRG-1 , for RTC, advertising content,and etc, can you please tell us where can we get from STM website.Regardsshreyas
Good afternoon,I've found few information about the available memory to use as for the GATT service in the BlueNRG-ms.I have a GATT service defined and I want to know if it fits in the BlueNRG and,if not, how much I have to reduce it For the second, ...
I am issuing the commands from AN4683 section 3.2, and the AT+CFUN=1 command times out without completing. Would there be example C code somewhere that can perform these steps with success? Thanks!
Posted on June 05, 2018 at 08:51Hello everyoneI am confused by documentation of BlueNRG and various description of exiting from WFI for Cortex-M0.What is going on when BlueNRG-2 is woken up from deep sleep by external gpio pin?Is the program continu...
