@rmtucker Could you please explain in weich was you connect the STLINK to the NRF Module to usw the Arduino IDE. Thanks

RE: 💬 Multi-Sensor: Temp/Humidity/PIR/ Leak/Magnet/Light/Accel
@NeverDie
Did you or anybody else could write to the NRF5xxx via the Arduino IDE and a ST-Link V2 programmer?
I find the DK for approx. 32€ a little bit to expensive for just testing.Edit: Maybe this one could work:

RE: High Power Consumption without any reason.
@sundberg84
I also unplugged the sensor, nothing happend to the power consumption in both states.The note is powered through an CP2102 USB 2.0 zu TTL UART on 3V3. Later I planned to power through an CR2450 coin cell.
Unfortunately I cannot unplug the NRF-Module because it is soldered directly to the following shield. (https://oshpark.com/shared_projects/uXIff7XO)
Could it be an faulty NRF-module?

High Power Consumption without any reason.
Hello Guys,
I made a MySensor-Sensor out of an Arduino Pro Mini 3V3 8Mhz Clone a BME280 and a NRF24L01 module. During sending the data my power consumption is about 17-18mA, which is often mentioned in the forum.
But in sleepmode there is a much higher power consumption of 4mA than I expected and also mentioned in the topics.Could you please give me a hint where I had to look for the high power consumption? LED and Regulator are removed.
My Code:
