Can you please send a link to the XM1110 firmware? Thank you.
I cannot find the firmware for the module on Sierra source. As my understand, this is a new Sierra product. Had it installed firmware when you got it from distributor? It yes, that firmware is the latest I believe
Please share any concern you have and help tick Solution under my comment if it answers your question
Which variant (UART+SPI, UART+I2C, etc) and version (5.1.1?) of the firmware do you want?
