Hi,

I am working on a sensor module design for a research project I am doing. I using an MSP430G2553 that I plug into a socket on my custom PCB. The MSP430 manages a collection of I2C sensors and then communicates data over Bluetooth. The Bluetooth module connects to the MSP430 with the hardware UART, 9600 baud rate.

 

I was planning on programming the MSPs with the Launchpad and then plugging them into my sensor module PCBs.

 

The issue I am having is that I am receiving no response over the serial connection when I try the setup on my custom PCB. I bread boarded the design prior to creating the PCB and it worked fine when the MSP was plugging into the Launchpad and I wired to that. I tried switching the RX and TX lines to see if I had flipped them but to know avail. The power is fine and the Bluetooth module successfully powers up and connects. 

 

Does anyone have any insights?

Was just looking over the LaunchPad schematic and realized I had forgotten to do exactly that. I just hot-fixed it and every thing is working smoothly. Thanks for the comment though, most likely would have saved me some frustration if I hadn't realized sooner.

I hate it when that happens I'm glad your problem was resolved.

Hello 

I am new in hardware field , so I have a question ,

Is possible to activate transreceiver module in the bluegiga (bluetooth) by simply connecting Tx,Rx,GND,Vcc into the corresponding micro-controller(msp430fg4618) pin without any boost of passive and active component?
