Weird behavior when breaking in an interrupt
Hello,I have a NUCLEO-WL55JC1 development board that I am trying to have communicate over subGHz RF.After configuring the RF module, I am trying to read what interrupts are generated based on different stimuli. To accomplish this, I set a breakpoint ...
Forcing a server to disconnect?
Hello ....I have an apk that seems to lose comms with a server. We have not been able to make it periodic or obvious as to the reason. We would like the server to timeout after 30 seconds of not receiving read/write rqsts from the client and force ...
STM32WB15CCU6: Cannot restore corrupt option bytes
For a project for one of our customers, we use STM32WB15CCU6 microcontrollers on a custom board. The boards are returning from the field with several of the option bytes of the microcontroller set to a different value than they were programmed with. ...

How can I set the right parameters for the SAI using PDM interface?
Hi, i'm using the STM32WB5MM-DK borad and i encountered some problems about acquiring data from the SAI using the PDM interface.On my board is mounted the IMP34DT05 microphone which requires a clock frequency between 1.2MHz and 3.25MHz to work. I can...
Cell chemistry advises for Lora
There are quite a number of cell chemistry for Lithium (and possibly others). Which one is good for Lora:Transmit time of 1.5 seconds or less, current 1C or less. Recharge 0.5C to be safe (may be 1C on spec.).Normal (non transmit) low duty cycle loa...
