Hi,About the stm32wl55 subGHz module. I choose FSK mode because of his higher flow rate than LORA. Question what is the preamble, i know his length can be tuned but what it is ?RegardsJP
According to the documentation: In TX mode, BUSY will go low as soon as the PA has ramped-up and the transmission of the preamble starts. The active mode switching time given in 5.7.8 Table 33 does not specify what PA Ramp time is for the *-to-TX mo...
Hi there,I am attempting to generate a simple FSK TX packet with the NUCLEO-WL55JC1 development kit, but I am struggling to understand how to enable the SUBGHZ radio and get it working. I have tried writing my own hardware interface with no luck, and...
PS: I don't want to use an external antenna
STM32WB55 bluevoice demo. Peripheral blinks blue, but turns red on SW1. Central blinks green -- on reset of central peripheral returns to blinking green. No code changes, but yesterday green blink was rapid today slow. I can't ask good questions yet ...
I'm currently looking into how to actually set the security modes and security levels for a BLE device build on the STM32WB55RG chip.I have found the method to get what the security mode and level is:tBleStatus aci_gap_get_security_level( uint16_t Co...
Does someone tried to have geolocation somehow with STM32WL Lora Stack?Supposedly it's included in the protocol using RSSI or TDOA against different gateways.Another way is to have direct link without gateway of known position nodes and the different...
Hi, I tested the board with the UART_TwoBoardPolling but I don't succed to turn the user button 1 into the user button 2. The LED stops blinking but nothing append. With the debugger, it is going somewhere but i don't see where... maybe hardfault ?
Hi there,I have a small question about the Radio IRQ lines on the STM32WL series. As far as I am aware, there are two MCU interrupts tied to the SUBGHZ radio: the RFBUSY interrupt (EXTI45) and the SUBGHZ_Radio_IRQ (EXTI44). However, when setting up t...
