1. Connect: Power, UART and Jlink. 
2. Prepare Putty.
3. Setup jflash-lite: Device is nRF51822_xxAA
4. Erase mem. 
5. Don’t load any soft-machine
6. Flash with “Reflector-1w_(6b)_UART_TS06_2.hex”
7. Power-cycle.
8. No LEDs flash, after startup sequence
9. You should see this:
   

TS06.3

1. Connect: USB and Jlink.  Prepare Putty
2. NB! This device is nRF51822_xxAC
3. Erase mem
4. Load soft-machine “s130_nrf51_1.0.0_softdevice.hex”
5. Load my software “Initator_1w_UART_TS06_3.hex”
6. Push the reset button – nearest the uSD card
7. Should see exactly this sequence: see this video
   

MCP

1. Plug in the little BLE dongle.  Note the serial# on the chip!
2. Connect MCP to the dongle.  Make sure you specify the correct serial# or you may connect to the JLink instead, and since it may ask to reflash the dongle, this could be bad.  If it does ask to feflash dongle select the “slow” option.
3. Start discovery.  This can take several attempts at 5 seconds each.
4. 
   Notice above, that a foreign BLE device (0x68644B269739… my neighbor’s) has been discovered!
5. Select “ts” from the list, and click “Select Device”.  Wait up to 5 seconds… If it connects you should see this LED pattern:
   

   Weasle words: BLE is a bit unpredictable at this point. It should connect, and you should see a list of characteristics.
   If not press “Connect”, or start over.
   If no services characteristics are printed then press “Discover services”
   

6. Click “Enable Services”

Running a range operation

1. Click last item in list, type in 2-digit hex#, and press “Write”.

   

2. If it works you should see something like this on the putty channel, and the MCP characteristic above the one you typed in will show the range in hex-centimeters with the bytes reverse.  Great huh  EF-FF => FFEF => -17cm

Looks interesting:

CSP package available that’s just 2mm x 3mm. QFN package available 5mm x 5mm.

I tried calling Microsemi sales but just got VM.

Track Your Active Life.

This stylish activity tracker blends the functionality of an activity tracking band with the look and feel of a traditional analog watch. The unique fourth hand tracks daily steps, distance and percent to goal right on the dial. The Metropolitan+ uses Bluetooth technology to connect to the Timex App on your phone that tracks daily activity, including steps, distance and calories burned. The phone app stores your data so you can access and analyze it at any time. This watch also features quick release straps so you can easily change your look in seconds.

From instruction sheet: 

I wondered if we had a hardware issue, or a software issue, or both.

I just tried to copy your measurement process with the Nordic eval board.  Here’s what I did, and I’m not sure of my workings, so check me out.

• First I read p21 of this document.

Notice the last note.  Maybe that’s significant for us?

• I looked through hundreds of loose resistors and found one that claims to be 10 ohms.
• Then I kind kludged it across the current measurement pins of the PCA10001, using my meter probes, like this.
  
• Then I ran my software and put the Nordic to sleep (allegedly)
• My meter looks like this
  
• Then I found an ohms-law calculator and plugged in some values.
  

Well doh!  1.2mA

I have to measure the voltage which is…. 

Learned something significant

It’s nice looking, and has a circular display.  1.5 day battery life!

Comments:

Here’s the trace after Scan2560m12msNoLeds.hex boots between the 12ms pulses.

The solid cursor is “A” and the dotted cursor is “B”. The pulse measured in the center of the rise and fall times is 11.8ms. The height is 127mV. The increase in current is 0.127/10 = 12.7mA. The power of the pulse is V*I=2.7215*0.0127=0.03456 watts. The energy of the pulse is 0.03456W * 0.0118S = 0.4078 mW-S=1.1329e-7 W-H.  

More troubling then the pulse is the 8.8mA the Nordic is drawing constantly. What is turned on (or what has been turned off might be a better way to look at it).
