Hi,
My client sends a locating signal at 433MHz using a CC1070 and is able to locate the transmitter using a handheld receiver. The transmitter also sends identifying data in UART format and now wants to receive and display the transmitter ID.
I have purchased a CC1020/1070DK development kit, but could only get the -868MHz version. I have done a BOM comparison between the -868 and -433 variants, and used SmartRF Studio with the target frequency, to identify the component changes required to convert the -868 to -433 and have made those changes to both CC1020EMX modules. But with a working transmitter, and the CC1020EB with CC1020EMX operating using SmartRF Studio, I'm getting -122dB of RSSI.
Has anyone here done a -868 to -433 conversion on this development kit? Does anyone have any advice on how I could proceed to debug this setup?
