RN4871 and RN4870 shares the same firmware. The firmware should be able to read the ID in in IC to differentiate RN4870 and RN4871,
Maybe the information block in your IC is damaged. Could you help share your PCB design and Schematics? I would like to check the power supply circuit of RN4871U. If the power circuit is not handled properly, information block could be damaged. Thanks. Martin

This is my PCB Schematics.
I found the same problem in google. --> https://www.microchip.com/forums/m954916.aspx Unstable voltage seems to cause damage to the Bluetooth.
