Thanks for your continuous help!
TomGeorge:
Hi,
The voltages look correct, why did you disconnect the battery in attachment B?
Att A
Att B
Att C
Where is the battery?
The batt is connected to V Batt.
TomGeorge:
Hi,Is the battery connected in Att A?
That is the arrangement in Att C, you have 3.27Vdc output, whats the problem?
What are you expecting?If Att C is not the solely power by li-ion, then show us the voltages when you are trying to power the system with solely the li-ion.
Tom....
PS. Can you post a pcture of your project, with battery connected, so we can see your component layout?
I have attached (refer to attachment A) my full schematic of my project, its about using simblee module to read data from ADXL362. The schematic is actually reference the simblee lilypad from sparkfun. LilyPad Simblee BLE Board - RFD77101 - DEV-13633 - SparkFun Electronics. the only different is just i am using the original rfduino usb shield, but sparkfun uses the 5V FDTI.
I have also tried to hook up my previous simblee board with different scenarios to see if there are actually some problem to power up by other sources, and i found out there are some problems. I have attached a full picture (Attachment B). Not working means i cannot upload any program nor read the data from the sensor. It shows UART TIMEOUT FAIL...FAIL...FAIL...
Please help. Many thanks!
