Resolved! porting project from STM32WL55JC (3.3V) to STM32WLE5CC (1.18V) - all running but no RF signal on Tx
Hi all,I have to port a working LoRa project from STM32WL55JC (3.3V) to STM32WLE5CC. First besides the JC (BGA) has more pins thatn the E5CC (QFN), anything else should be the same (expect maiy EXTI which te project does not use).Now my the issue: Th...
Documentation of STM32WB Bluetooth® Low Energy (BLE) wireless interface
I'm trying to find a proper documentation for the ACI commands of the bluetooth stack included in the STM32CubeWB MCU Firmware Package. We're running the stm32wb5x_BLE_Stack_full_fw on one CPU of a WB55 and our application on the other. Our applicati...
How can we access PB0 alternate function RF_TX_MOD_EXT_PA to control external RF power amplifier?
Hi,I need a way to control external power amplifier enable to turn it on only when transmitting.I read that PB0 has alternate function intended for this (RF_TX_MOD_EXT_PA).Can I use this function to control the external amplifier SKY66118-11? This is...
