We designed and manufactured a custom PCB with DA14585 and IMU sensor on it. For testing and debugging we have placed 8-pin SMD jumper(J2) on the custom board. For available pins details on jumper please find it in the attachment.
Using jumper wires we have connected J2 jumper to the pro-development board for debugging and testing. Connection details find it in the attachment.
The code we developed for our application is working fine and we have created the .hex file to upload using smart snippets for estimating power consumption with power profiler. After uploading the code, we ran power profiler to see the power consumption, the graph it was showing an only constant value, there is no change in the profile when the device goes from one state to another(like advertising to connected state). Please find a snapshot of this in the attachment.
Do we need any extra connection from the pro dev board to the custom board to run the power profile? or the jumper J2 connection is fine?
If we need to perform the power consumption test do we have any other methods or any other instruments can we use (like DMM, Oscilloscope)? If so where we can connect the external instruments to the pro dev board, that can give us the best results?
Do we have any instruments or methods which can test the BLE range for custom boards?
