4.2.5 Automatic bootloader on NORA-W10 EVK
The “esptool.py” flash tool supports automatic entry to the bootloader on the NORA-W10 EVK
without pressing the BOOT button and RESET the module. To use this functionality, you need to
connect the following pins:
• RESET to IO19 (CTS)
• IO0 (IO zero) to IO26 (DSR)
The jumpers CTS (J14-8) and DSR (J14-7) should also be removed so that they do not interfere.
☞ It is not possible to use the Hardware Flow control or the DSR signals on the UART while using this
setup.

4.3 Output power configuration
4.3.1 NORA-W10 series
To operate within the regulatory output power limits, the integrator must configure the module using
the instructions given in this section.
The following power configurations for Wi-Fi and Bluetooth low energy are only valid for the official
esp-idf git repositories.
4.3.1.1 Wi-Fi output power configuration for version v4.4
The components required to perform the output power configuration and RF calibration are included
(with examples) under the product subfolder in the u-blox SHO-OpenCPU GitHub repository [9].
4.3.1.2 Bluetooth low energy output power configuration
No output power configuration for Bluetooth low energy is required. Using the default settings, the
module operates at ~6 dBm, which is within the regulatory limit for NORA-W10.
