I-CUBE-LRWAN flash optimization
Hi,I need more 4kB of flash memory. Can I achieve this easily and safely by removing some not used functionality in the I-CUBE-LRWAN project?I suppose Lorawan Class B and C featues will not be needed. Can I just exclude this files from the project an...
Resolved! STM32WB Fails on SHCI_C2_BLE_Init
Hello! I'm working with a custom STM32WB10CCU board and can't seem to get BLE working.Here are the details:I have no LSE on the board.. just HSE. I'm configuring RFWKP to HSE/1024 and RTC to HSE/32 (I know that LSE is strongly recommended -.. but fro...
Recommended TCXO for STM32WL Design
We design a new product where we use STM32WL microcontroller and in the datasheet ST is recommended to use NT2016SF-32M-END5875A, it was not in stock everywhere. We planned to use the ECS-TXO-20CSMV-320-EY-TR TCXO in our design. Please share your rec...
STM32WLE5CC MCU brick when trying to set Brownout Reset level
GreetingsI have been trying to set the BOR option byte via software in a STM32WLE5CC (as part of a RAK3172 evaluation board), but even following various guides i have not been successful in this endeavor, often resulting in the MCU being bricked and ...
SUBGHZ_PHY on STM32WLE5CC
I have a problem with SUBGHZ_PHY on STM32WLE5CC.I have 4 devices as follow:Device1: STM32L0XX device using B-L072Z-LRWAN1(SX1261)Device2: same as Device1Device3: STM32WLE5CCDevice4: same as Device3Device1 and Device2 can communicate with each other. ...
Is there any examples using the Lora E5 ?
Hi I have the Lora E5 development kit from seed, and able to send data to the server using the built in AT commands. I cant seem to find any guides, and basic examples on how to use the built in STM32 and Lora. Can anyone point me to the right pages...
Resolved! [STM32WB] [Zigbee] Node name
Hello,I have ran and modified few examples of applications for Zigbee on Nucleo STM32WB.I have registered my STM32WB as a node of my existing Zigbee network and it works fine.My coordinator indicates me that the Zigbee model of the node is "STM32WB"....
Resolved! What is the soldering profile for the STM32WB35CCU6A MCU?
The operating temperature range for the above MCU is -40 to 85 deg C (105 deg C junction). Does it mean that the maximum temperature for soldering is 105 deg C, or does it just mean that the MCU will shut down at 105 deg C? I would appreciate it if y...
Resolved! Found a bug in the Hardware timerserver source file for STM32WPAN Middleware. If RestartWakeupCounter function is past a zero value in its "Value" parameter, then the function will complete without re-enabling the RTC_WAKEUPTIMER.
The case described occurs when multiple timers are used and one repetitive timer is tiggered right after another repetitive timer. The first code snippet below shows the current implementation and the second shows the fixed code.static void RestartWa...
Bugs in Mailbox communication code of STM32WB
Hi, I have found a few bugs in the Mailbox communication code of the STM32WB (which is responsible for letting CPU1 and CPU2 communicate). But other Dual-Core MCUs potentially could have the same bugs.The bugs are not security-critical, but they caus...
