Hello,
I received the bq 500215EVM-648. And I tried to start up with no receiver (User’s Guide, chapter 6.2.2.1). The Problem is LED D2 doesn’t flash, it only turned on, and no Ping form the transmitter is sent.
The thinks I did.
Set the Power supply to a maximum Current of 2,7A and the Voltage to 12V.
I checked the polarity from the connection.
I also checked the resistors on the board.
I reset the Bq500215 over the reset pin.
I change the resistor R9, to get an other LED Mode (I placed 48k7). No lights (D6, D7, D8) turned on.
What can I check to get the board started up and to measure a signal on tp15.
Thanks for tips.
Tobias
