Resolved! Why now ERR_UNKNOWN_HCI_COMMAND return value to aci_hal_get_anchor_period()?

Hello - I was using the results of aci_hal_get_anchor_period() just a few months ago, but now in v1.13.3 BLE_full_stack, it is returning ERR_UNKNOWN_HCI_COMMAND. Is there some command that needs to be sent to enable getting the anchor period? If ther...

Resolved! How to re-enable general scanning after terminating a direct connection establishment?

In v1.13.3 BLE full_stack it looks like general scanning is locked-out forever after terminating a direct connection establishment procedure. Using the Nucleo dev boards as a master and a slave, start general scanning with aci_gap_start_general_disco...

Resolved! When using a GPIO pin as output, is the offered voltage stable? Imagine I want to use it to enable (or disable) an LDO, is it okay to connect the GPIO output to the enable pin directly?

Resolved! How to set the RF output power of Stm32wl55?

Hi, How can I set the RF output power of stm32wl55 in a LoRaWAN application?  I have Nucleo board, but it seems transmission power is adjusted automatically. The distance between the Gateway and Nucleo is a bit far, so I need to increase TX power. If...

Resolved! Hi I am new to STM, I am using CMWX1ZZABZ_LoRa_Module, I just want to know if I can use USART1 and LPUART1 simultaneously. Are they Independent of each other?

Resolved! STM32L series with LORA Module(1.8V)

Hello everyone,I want to make a project with STM32L series and LORA module and battery optimization is essential. I am going to run MCU under 1.8V but I am still not sure about LORA module. I am seeing support 1.8V operational mode. I assume if I hav...

Resolved! Is the reduced power comsumption the only advantage of using the RFO_LP output respect RFO_HP? Can I use the same RF matching network for RFO_LP and RFO_HP outputs? Any disadvantage of using the same RF matching network for both outputs?

I am developing a hardware design using the STM32WLE5JCI6. As a reference, I am looking at projects "MB1842.PrjPcb" (reference design) and "MB1389.PrjPcb" (Nucleo-WL55JC1 design files)

Resolved! How I Program the CPU2 memory area using STM32CubeProgrammer?

I'm trying to understand how I program the BLE Stack and FUS in the CPU2 of STM32WB55G (1Mb). When I use the binary available of ST repositoy, in default mode I program the "stm32wb5x_BLE_Stack_full_fw.bin" in address started 0x08000000, but in the r...
