RAK15006 FRAM sleep mode

Hello,

I’m using a RAK19007 + RAK4630 for a LoRaWAN node project. I want to use the RAK15006 FRAM memory to record data over time. This works, but I can’t get the memory to go into sleep mode. I’m using slot C with IO3 for WP. Even with FRAM.entersleep() and cutting power to WB_IO2, I still have a power consumption of 1mA according to the power profiler. Do you have any suggestions, and perhaps code to put the FRAM into sleep mode?

Thank you for your help

Hi @nico_la ,

It can be that the 1mA you see is not from the RAK15006 module since WB_IO2 will cut out all the connection to the FRAM.
