I'm working on the EFR32BG22 MCU firmware from Silicon Labs, and I want to use two different Modems from QUECTEL (BC95-GV@9600 bps and BC660K-GL@115200 bps). This FW, must have the following funtionallity: 1. At first, the code runs with a initial...
when run the program I want to get "48 65 6C 6C 6F 20 77 6F 72 6C 64 2E" ,which mean "hello world",while I get "62 AC 3B B8 3E AC 3B 09 FF ".But in baudrate 115200,it was right. The register value as following: 0 Kudos Reply 09-28-2023 09:51 AM...
