Wireless Peer to Peer communication w/o user intervention pairing
I'm trying to find out the wireless technology that I can use for peer to peer communication. The main requirement is to have good data transfer speed (at least 500kps or more), pairing process should be without user intervention and the devices will...
Unlocking a STM32WB55CGU6
I have an STM32WB55CGU6 processor. I initially started with updated the FUS from v0.5.3 to v1.0.1 via the STM32CubeProgrammer. This update was successful. I then proceeded with trying to load the v1.2.0 FUS. However I got the following error:After do...

Updating advertisement packet after waking up from standby mode (WB15CC)
Hi,My application (WB15CC) stays most of the time in standby mode transmitting the advertainment packet. After a couple of minutes, the advertainment packet must be updated. When I try to update the packet after waking up from the standby mode, the f...
Resolved! STM32WL55 no rf
Good dayI am using the STM32WL55 chip for a project. I did preliminary tests using the NUCLEO-WL55JC2 Development board.I created a custom PCB following the design of the Development board.When I program the custom board with the same firmware that w...
STM32WB55: C2 randomly enters spin loop
I find that when entering deep sleep/range 2 using aci_gap_set_non_discoverable(), C2 would not reliably enter the ultra low (~4uA) power consumption mode, current would jump to ~5mA. I am using stack 1.18 and even 1.19. a) Calling aci_gap_set_non_...
Resolved! SPI: changing CPOL between transmissions
I have 2 devices on my SPI bus that need different CPOL settings. both use CPHA = 0 and the SPI peripheral is configured to use Motorola frame format.Communication works with both devices if their respective CPOL setting is set in CubeMX (and thus fi...
