How to change ADC's Number of Conversion?
Hi, there:We need to change the Number of Conversion of the ADC during the run in STM32WB MCU. It is configured with multiple channels and with DMA.(1) Can we just de-initialize the HADC and re-initialize a new one? Will it affect the interrupt and D...
RTC Alarm interrupt after 48 days in ST LoRa middlewares. What it happens?
Hi,I have a question related to the working principle of RTC in the LoRa middleware I-CUBE-LRWAN and STM32CubeWL.I'm working on the firmware for custom boards based on development boards both B-L072Z-LRWAN1 and the more recent NUCLEO-WL55JC1.My proje...
[STM32WB55] Is it possible to change UUID in Beacon mode?
Hello,I want to advertise custom data in beacon mode using UUID, Major and Minor Value. In my understand It is not available to change those value when the beacon is working. Because UUID, Major and Minor will be set when beacon starts.Is there way ...
Resolved! BLE slot allocation error
I read in this document about the concept of BLE slot allocation. I experimented with 5 STM32WB boards, one as master the four as slaves), and encountered an error I didn't understand.The master issued `aci_gap_create_connection` to each of the four ...
STM32WB15: do you need to pull PH3-BOOT0 high in order to program the authentication key or can you just program it booting up with no firmware image programmed in Main Flash memory and PH3-BOOT0 pulled low? Both ways should boot into System memory right?
Details in the SECoreBin/readme.txt file for the STM32WB code says that the MCU needs to be booted with PH3-BOOT0 pulled high in order to program the Authentication Key. I can't find any other documentation that indicates that this is true. Does the ...
Different TX power level for advertising and connection (STM32WB)
Hi,is there any option to set different tx power level (aci_hal_set_tx_power_level) when device is connected and is still advertising in background? My goal is to set minimum tx power level for advertising and maximum for connection, when both states...
STM32WB CPU2 stops after several connect/disconnect sequences
I expirence very strange behavior on STM32WB. After 6 connect/disconnect sequences, CPU2 stops working. I'm not receiving any IPPC interrupts. Last event I get, before CPU2 stuck, is ACI_ATT_EXCHANGE_MTU_RESP_VSEVT_CODE. I tried to call hci_reset fun...
I'm looking for V1.3.0 of I-CUBE-LRWAN
On the website I can only download the latest version (2.1.0 in this case)We are working on a project that uses version 1.3.0 + our custom changes and we want to get version 1.3.0 to differentiate the original from our changes
CPU2 on STM32WB55 seems to wake every 2 seconds even without a connection or advertising.
I've been doing some current draw analysis of our product and I am trying to get the best idle current that I can get. We have a mode where there is no BLE connection and no advertising. Essentially no BLE communication at all. In this mode I woul...
