I am trying to follow the instructions here to connect to the RakWireless 3172 Breakout Development Board. RAK3272S Quick Start Guide | RAKwireless Documentation Center. I provided my setup and the example setup that is described. However, whenever I get the AT errors. Does anyone have any advice that could help me resolve this issue?
Correct. I have had no luck with UART to flash custom .bin files so far using the RAK3172 breakout board. One of our existing products uses UART to flash bin files, and we would like to use the RAK3172 as a drop in replacement using this same method. The UART works with AT commands using the RAK Serial Port Tool, but we need it to flash our own bin files due to some additional complexity we need to account for on our device.
