HI all I am using blurenrg2 m2spa blue tooth chip . Its operates as a network mode . it communicating with host controller through UART 115200 baud rate . here i configured chip as peripheral role and st ble sensor app acts as a central device , wh...
I´m using the STEVAL-IDB008V1M board, and the BLE_Throughput example code provided for it.I would like to increase the throughput in this example, how can that be accomplished?I have tried a lot of different things to accomplish this, but still in th...
Hello everyone i'm discovering BLE communication through STEVAL-BNC002V1.Then i want to add new characteristics with fields calculated with values from sensors. I read the documentation but i can't understand the function aci_gatt_db_add_char.I will ...
In order to keep track of the Time of Day I would like to implement a time tick.None of the timers run (other than the virtual timer) when the bluetooth module goes into low power mode. I would like the CPU to only wake up when there is an external e...
Hi,I have a NUCLEO- F401RE board with the X- NUCLEO-S2868A2 expansion shell and i want to test the examples, provide by ST, that the X-NUCLEO-SUBG2 folder contain.I import the border router and both of the udp's projects to see how they works (one by...
Hi,I am planning to make subGHz Border router by using Contiki border router example. For Internet, I would like to integrate the Wifi, GSM and Ethernet. I don't want to use Rpi or Beagle bone. I am planning to use STm32 and make my own IPV6 Internet...
Please see the configuration in the pictures below. I did not modify any register manually.I think that as preamble and sync word are different in each mode, I should not receive anything ...
Hi,I started importing X-CUBE-SUBG2 software in to STM32cubeIDE 1.6.0. I am getting lot of errors when I compiled for Nucleo-F401re. Binaries works as explained in user manual. But, whenever I import the project, I am getting errors. It looks like t...
We've measured the start-up current on BlueNRG1 at around 4mA for 60mS. We've been exploring the cold_start_config and we think the biggest part of the delay is HS oscillator settling time. I believe a few hundred uS is typical for XTAL startup For a...
I am evaluating the STUSB1602 in combination with a STMF103 in a dual-role port, UFB (usb-device) application. In source mode, the device should provide type-c current 5V 3A or 5V 1,5A. Do I have to connect the BMC interface to advertise power sourci...
