Issue: “Start sending” stuck when firmware upgrading
Setup: RAK811 915Mhz- OTAA, USB to Laptop
Details: I deleted the memory and installed the bootloader (RAK811_BOOT_V3.0.2.bin) onto the RAK811. Next I tried to install the latest firmware for my band (RAK811_v184.108.40.206.H_20200810.bin). I purchased it recently and originally had the beta version on it, which i can’t find anywhere. Within the RAK LoRaButton Upgrade Tool I am recieving a “Start sending…” message with no movement of the progress bar. The Led2(Tx) keeps flashing as well. The “Upgrade Success!” message never displays and I an not able to write or read from the RAK Serial Port Tool.
I enter the following in it:
AT cmd error.
Here is a screenshot after I have installed the bootloader and try to install the firmware:
The message never advances and the firmware never installs
