Note that once the upgrade has successfully completed, the RN52-EK will have RN52SRC firmware with DFU-over-UART enabled for future DFUs. It is highly recommended to save the current firmware on the RN52-EK using the save current firmware option in the “Upgrade Action Selection” step while running the Microchip Bluetooth DFU Utility. The RN52SRC DFU (.dfu) image available on the Microchip RN52 web page can be used with the Microchip Bluetooth DFU Utility to upgrade the RN52 module on the RN52-EK with standard RN52 firmware to RN52SRC firmware. The RN52SRC firmware can be evaluated on the RN52-EK development board. RN52SRC Bluetooth® Audio Module Command Reference User’s Guide

Yes two RN52's can be pared together, you have to Upload the SRC "source" firmware on one to make it a masterįollowing are instructions on what to download, and how to pair them, from: IF and WHEN I get that completed, I will post it. I am attempting to write some instructions on doing the firmware upgrades. If you reconnect the upgraded RN52 using the FTDI basic, and put the RN52 into command mode (by connecting GPIO9 to ground), when you enter V the module will show it is running Version 1.16 the final reboot done by the DFU utility will be unable to communicate to the RN52 after the firmware upgrade.

When the upgrade finishes, it will INDICATE that the update failed. Note, when you upgrade one of the RN52's to v1.16 you must use the mini USB and choose to update via USB. Release notes are available for the v1.00 SRC firmware (to set up the RN52 as the MASTER) and for the v1.16 slave. Good luck finding the firmware release notes on the version 1.10 firmware. Hardwiring the two pins to 3.3v in, solves the problem. If you have the button included, it is extremely difficult to know WHEN to press the boot button. We believe the DFU utilility probably does at least one reset during the boot up process. this forces the module to boot up every time it is reset. Instead, connect the 3.3v in to both the 3.3v in pin AND to the power enable pin. To do DFU firmware updates, our suggestion is do NOT use the momentary button in the hookup guide. One is needed to connect using UART and the other is needed to connect via USB. We used Sparkfun FTDI Basic and a Sparkfun Mini USB Breakout. Bear in mind that you MAY need to use two different connection BOB's to do the trick. The documentation in the sparkfun hookup guide is close but you must follow it VERY precisely. We could find NO documentation anywhere on how to do it. I won't say it was easy because it definitely was not. Each pair used a different master slave pairing so there would be no crosstalk between them.
Once you have that, you CAN set up a couple of breadboards using the appropriate "interface boards" and simultaneously connect BOTH modules and configure (Pair them) to talk to each other. I know that my adult son dug around on the Internet for many days before he found this firmware and the release notes. You must flash the firmware on ONE of the modules using the "rn52src-i_rm100.dfu" firmware.
One RN52 must be set up as a "master", the other must be set up as a "slave".
