I am working on product which uses particle P1. It is currently going through FCC testing. Need help in figuring out the current firmware for running the tests. The product also has a BLE module hence the firmware is needed to perform the co-location test.
- The download in the certification guide has 2 sets of binaries BM-09 and BM-14. Which is the correct set of binaries for P1?
- The tests are run with commands on a UART port. Which UART on P1 is used for this? Could not find this in the document/guide contained in the download.
I have tried flash the firmware however the scripts provided give the following error(Reading CDC header failed) :
The serial port is connected to PA9 and PA10 pins on P1.
The RX and TX pins are properly connected to USB-Serial. I get the following message on terminal upon boot:
Any pointers to resolve will be great!
