Hi,
We’re developing a BLE-based product on the nRF54L15 (InsightSIP ISP2454-LX) using nRF Connect SDK v3.0.2, with MCUboot enabled for DFU.
Our BLE application is based on a custom service and configured to use +8 dBm Tx power. Initially, everything works fine. I am getting good range with +8 dBm Tx power.
I used following macro to achieve same.
CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=y CONFIG_BT_CTLR_TX_PWR_PLUS_8=y
Problem:
After enabling MCUboot via sysbuild, the BLE behavior changes. I am getting ~5 times less range.
We confirmed that this issue only occurs after enabling MCUboot. Without the bootloader, range is very good.
Please help me to get same range after adding MCUBoot.80015.prj.conf5123.mcuboot.conf1803.sysbuild.conf
