I have an STM32WB55 board. I used the CUBEMX to generate a template that both activates the internal temperature sensor and BLE module.However, if I ran the program generated, it will be blocked in the "hw_timeserver.c" at line 566, which is:while(__...
Any program that I generate using STM32CubeIDE for the STM32WB with BLE enabled hangs until I comment out the following line. What need to change in the initialization sequence? /** * We should never end up in this case * However, if due to any...
HI. I bought the STM32WL lora HF Package (lora getaway + lora sense)I programmed the gateway as appear in the youtube here the link(https://www.youtube.com/watch?v=uJU3YM1MWN4)It worked well for 1 month, suddenly I lost the signal from the node, and ...
I have been trying to get receiving of custom(32bit preamble, 2 byte SYNC word, fixed size) FSK packets working. It seems to work fine only sometimes. Sometimes the sync word shows up in the received data buffer and sometimes it isnt there. I honestl...
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...
