The original module works great on the previous version of my assembly, the new assembly with the Mouser part does not show an SSID with a tested, working external UFL antenna attached. I originally loaded the AT non-OS firmware version 1.6.1 on the original board and upgraded it to version 1.7.4 recently released and it works fine. I loaded the 1.7.4 version on the new assembly and no SSID shows in my network list. The firmware loads fine with the ESP8266 Download Tool version 3.8.5 Here are my settings
ESP8266_NonOS_AT_Bin_V1.7.4\bin\boot_v1.7.bin 0x00000

Along with the SSID not showing in my network list after rebooting (removing the jumper for the boot option) I connect to the module using Tera Term and when rebooting receive a bunch of random looking characters, but no READY prompt to accept AT commands. I get the READY prompt with the original assembly design with the non UFL ESP-WROOM-02 module but not with the new one. Again, the circuit design is identical. Here are the characters I get when connected to Tera Term with the new UFL module. Perhaps someone will recognize these characters and now what is going on.

I appreciate any help or any information provided. I am thinking the module is failed in some way, but it flashes fine every time.
Thank you .
