I have tried to build a custom Weather Station firmware according to the guide in https://github.com/ruuvi/ruuvitag_fw
I Modified only the BLE_TX_POWER to 10 and APP_CFG_NON_CONN_ADV_INTERVAL_MS to MSEC_TO_UNITS(5000, UNIT_0_625_MS). The firmware built without errors and made the DFU package with the --debug-mode -flag as described in the guide. After that, I successfully uploaded the firmware to the tag with iOS nRF Toolbox.
After the upload, the red LED on the tag is constantly on as if the tag doesn’t get past the bootloader or something?
Any idea what went wrong? All the help is much appreciated.
