For evaluating the WB55 i would like to have software on a PC that can accept data from the Nucleo board over BLE. Since my PC doesn't have the latest Bluetooth version i want to use a WB55 as the radio. Zephyr RTOS has an example that would make the...

I tried flashing PWR_STANDBY_RTC and PWR_EnterStandbyMode examples both has sleep current of 590uA. How do i get the datasheet value of 600nA standby current or atleast something less than 10uA.

My application only needs to send data once every few minutes during which time i can save power by turning off the radio. I don't see any examples that do it, they don't even have a deinit function.

With the throughput example if i use 2 WB55 boards, the maximum throughput that i get is 2KBpsDT = 2160 bytes/s lost = 0If i use my phone with PHY1, i get 90KBps+ and with PHY2 sometimes its 150KBps and sometimes 15KBps, on download. With upload its ...

I followed this[1] URL to update FUS and wireless stack, it failed and now i can't get wireless to work. All the examples are hard faulting. My FUS is still in version 0.5.3Reading 32-bit memory content Size : 4 Bytes Address: : 0x2...

I was thinking of buffering up data in RAM and then push it out once full. If i only need to use the radio once every few minutes or so wouldn't it save power by turning off the radio and only turning it on when needed. With an Android phone as maste...

It seems once flashing is done, i need to remove the jumper in JP5 that connects VDD to T_VDD or else the level shifter will burn 600uA+ of current.

Shouldn't current be measured at JP3 and not JP2?

Fixed this by first erasing all sectors from the "Erasing and programming" section of the programmer GUI and then flashing the FUS bySTM32_Programmer_CLI -c port=usb1 -fwupgrade stm32wb5x_FUS_fw_1_0_2.bin 0x080EC000 firstinstall=0

Or is it possible to flash the original wireless stack that came with the board?
