I have a BLE application running on BlueNRG chip. In one moment I want to pause Bluetooth communication and put the device in the deep sleep. It should wake only by GPIO interrupt. Then, the BLE stack should be active again. Unfortunately, if I call ...
We have a L152RE module connected to a RF transceiver called X-NUCLEO-S2868a2. So, our mission is to measure some frames received from a water gateway by WMBus. We have implemented the firmware SUB1GHZ (written by ST). We receive the first block of t...
In all ST devkit code, the commandaci_hal_set_tx_power_level(0,25)is used, but changing the parameters has no effect on the transmit power (is always about 0dBm).
In a non-encrypted BLE link, the device falls back to the level of minimum power consumption (STOP_NOTIMER) between connection events. In an "LE Secure" link, the CPU is kept active. Why, and what to do about that?
PA11 and PA12 are powered from VDD_USB.So, to use PA11 and/or PA12, we have to have the VDD_USB domain powered-up.I can't find any documentation of the expected VDD_USB current draw when the USB functionality is not used.In a previous project, I reme...
Which is the state between two advertising events for the calculation of the battery lifetime?Shutdown or Deepstop?Is the current profile shown in the plot obtained when exiting shutdown or deepstop state?Thanks
I'm having issues with the BlueNRG multifunction timers when using the sleep low power mode (SLEEPMODE_WAKETIMER). I've stripped down my project to create a minimal reproducible example which is described below.A virtual timer is being used to period...
Hi,I am using a BLUENRG-M2 module as a Network Processor (controller) and an STM32L4 MCU as a host.I am using some sensors, and I want to do periodic measurements (e.g every 5 min) and put the host in SLEEP mode (while not measuring) and l want the d...
I am using BLUENRG-M2 module as a Network Processor (Controller) and an STM32L4 MCU as a host. I want to make the device connectable via Bluetooth during a limited time (e.g 30 seconds) then put the Controller to SLEEP mode (e.g 30 seconds) to save e...
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...
