I am looking for a cheap Bluetooth Low Energy module to design into a sensor, and I saw the MxChip EMB1061 for $2.48 on Mouser and Digikey.  I have used the Microchip RN4871 in the past, but I am looking for something newer.  But support for the MxChip product (from China) looks sparse.  So I wanted to see if anyone here has used that chip.  It has been out since 2017, so I was hoping someone could say how hard or easy it was to connect to a Microchip microcontroller UART using the AT commands.
