  • Seeking Effective Flash Protection Methods for 54L05 Chip

    Hello everyone, I am currently working on implementing the flash protection feature for the 54L05 chip. My objective is to safeguard the code storage area from unintended erasure or overwriting during program execution. I have attempted to use the fprotect_area…
  • Cannot connect to BLE device from iOS

    Hi everyone, I’m designing custom hardware for my application using the nRF54L05 MCU (v2.9.0) . However, I can’t connect to the device from iOS — the connection always fails (it just keeps trying to connect; see the attached image). I initially suspected…
  • Adjust BLE Transmit Power in Code

    Hi everyone, I'm working on a project using the nRF54L05 (v2.9.0) and I'm currently facing an issue with BLE. I want to change the BLE transmit power , and so far I’ve only been able to set it via the prj.conf file using: CONFIG_BT_CTLR_TX_PWR_ANTENNA…
  • Inquiry on Using Primary Slot Only for nRF54L05 in MCUboot with SPI-based Firmware Update

    Dear Nordic Semiconductor Team and Community Members, I am currently working on an nRF54L05 project where I aim to use only the primary slot in MCUboot due to memory constraints. Instead of the backup slot upgrade mechanism, I want to implement a…

  • nRF54Lxx - reset circuitry

    Dear all, I am wondering, what is the reason for C13 being 3.9pF for QFN package, while there is no capacitor on WLCSP reference design? Could we use like 10nF instead? From what I see, this is a part of low-pass filter for RESET line from external…
