BlueNRG-1 high consumption in low power mode

Hi!I'm using BlueNRG-1 to beacon some messages.I tested a simple scenarious:100ms advertising messagesAdvertising with no connections allowed (ADV_NONCONN_IND)disable all GPIOsdisable debug printf and UARTI use the BLE_BEACON sample code with SDK 3.2...

What throughput should I expect for two BlueNRG-2's in SPI_DTM mode with DLE feature enabled?

I have ported the BLE_Throughput_EXT example for two MCU/BlueNRG2(DTM) setups to communicate with each other. I was getting around 34 kbps. When I implemented this example on a single setup and configured it to send out Notifications when connected ...

Why does BLE_OTA_ServiceManager example in BlueNRG-1_2 DK 3.2.0 implement application level CRC?

Doesn't the BLE specification already include a 3-byte link layer CRC field? Is this just for extra precaution when dealing with delicate firmware data?

Any difference between X-NUCLEO-IDW01M1 and X-NUCLEO-IDW04A1 ?

Right at the moment I have 2 X-NUCELO WIFI expansion board, X-NUCLEO-IDW01M1 & X-NUCLEO-IDW04A1. I am pretty confused, which one to use for an NUCLEO-144 STM32-Cortex M4 ?Is there any difference between the 2 boards?Which one is easy to manipulate?t...

In the MFT routine provided by bluenrg-2 Navigator, MFT1 is timed at 500ms, the interrupt function LED lamp flips, and the flip cycle read by oscilloscope is 250ms. Why? Expect an answer.

Is there a document that describes the Python data types for events received by the BlueNRG GUI script?

I have a device sending notifications to a BlueNRG-2 Eval board (STEVAL-IDB008V2) configured as central/master. I modified the script file ATT_MTU_extended_packet_len_Master_Security.py to work with my device. Everything works until I receive a notif...

Documentation for BlueNRG GUI Script Utility Commands

Is there more documentation somewhere for the BlueNRG GUI Script Utility commands? There is just a table in document UM2058 with very little detail. One has to guess and use the error messages from Python to try to figure out the command parameters...

BlueNRG-2 broadcasting

Hello,I have a few questions regarding the use of the BlueNRG-2 deviceI am building a system where I have to send small data packets (10 bytes) from 1 unit to 10+ units. I am aware that you can only have 7 simultaneous connections, but I am wondering...

Preferred way to temporarily disable sourcing with STUSB4700/STUSB4710

Hello,we would like to add a charge functionality via USB PD for an USB hub. Charging should be possible for the upstream port, e.g. the host shall be charged. The tricky part is, that the charge process has to be activated and deactivated during run...
