Hello,
I purchased the gas sensor platform reference design with the LMP91000 and BLE bluetooth module. I want to use it with an oxygen sensor but cannot figure out how to switch it to oxygen mode from the default CO mode.
I purchased the CC debugger and downloaded the Smart RF flash programmer and successfully updated the firmware on the module in the Smart RF software.
I have also downloaded the IAR workbench and the firmware from TI website. I opened the firmware file with IAR workbench, just like the reference guide instructed, and put an "x" next to CO mode and removed the "x" next to O2 mode.
But I can't get past this point. I can change the code using the IAR workbench software but I can't upload any firmware changes to the gas sensor device in this software. Conversely, I can update the firmware of the device using the Smart RF flash programmer software but I cannot actually change the firmware to my desired oxygen setting using this other software. The user guide does not state how to upload firmware changes made in IAR workbench to the device. How do I upload the changes I make to the firmware in IAR workbench to the physical device? If I fix the problem, will the iPhone app automatically recognize that the device is in oxygen mode and plot data accordingly?
Thanks,
Will
