The image is the current when sending data ,the first current peak is about 200mA ,the second peak is about 60 mA.
Is this ok?
The whole process lasts about 6ms.
The tag is in deepsleep before sending data.
Can you elaborate Which hardware and software are you using ?
We are using the schematic same with dw1001,but changed the power ICs with which we can bought from china.The dw1000 driver api is “DW1000 Device Driver Version 04.00.06”
It’s the DC-DC chip charge the cap after enable it.
When reduce the cap value after the dc-dc chip,the current can reduce lower
Thanks for coming back with the explanation.
Out of curiosity which DCDC part are you using on your design ?
