– Open the first characteristic (Generic Access 0x1800, this is the device name) Open the app, you should see the RN4870 (it will not have the same name), connect and the LED should change to 2 quick blinks every second.

Here I am using Android BLE Scanner by Bluepixel Technologies LLP but there are many similar apps.

Power the module, then use a BLE scanner app to find the beacon. Remember these are 3.3v devices so use 3.3v not 5v. New modules have a basic beacon set up and we can use this to test if the module is working or not. The previous diagram had the LED on the wrong pin and wired backwards…

The data sheet has full details for the other pins. Remember that RN4870 RX goes to usb adaptor TX and RN4870 TX does to usb adpater RX. These are all you need to use the module but it is a good idea to add a LED to Pin 30 so you know if it is on or not. The pins we are initially interested in are: The boards were designed from the datasheet and implement the 2 pins for the i2c and the 2 for the I/O. See Jon’s Twitter feed for pictures.ĭavid Ashmore kindly shared the Gerber files for an breakout/adapter board he created Jon Raymond contacted me to say he has created his own breakout boards (which look very nice) and is hoping to release the designs at some point. The only one I can find is the RN4870/1 Click from MikroElektronika. I am surprised that there are not more pre-made breakout boards for this module. This allowed me to use 2 pads to solder the wires which made life a little easier. You will notice that I used different pins for GND and VCC from the RN4870. The extra pin/socket on the end is not used. I simply connect the wire to GND when I want to enter programming mode. This one has a wire connected to the programming pin. Here is a second board which is slightly smaller. The connections are arranged to match the usb/serial adaptor I am using. The jumper is a simple way of connecting pin 18 to GND. With pin 18 brought to GND when the modules start they enter programming mode. The jumper is connected between pin 18/P2_0 and GND. Not the best soldering I have ever done but the board is very small and the iron tip has seen better days.

I mounted the module upside down so that I still have access to the pads should I need to add more connections later. A basic breakout board can be built if you have fairly steady hands. The RX4870/1 is a very small SMD board which makes it a little difficult for hobbyists. Same page as above, click the Documents tab and scroll down.

User guide, data sheet, firmwares and update tool. Most questions, if not all, will have already been answered on the forum. These modules are more expensive that the common hobbyist modules like the HM-10 but they far more advanced, well supported with full data sheets and a user forum. The ones I have are the RN4870-V/RM118 version. Image from the Microchip RN4870/1 data sheet. With shielding, without shielding, with antenna, without antenna, all pins available, only basic pins available. The RN4870/1 is available is a few different sizes/configurations.

Software Configurable Role as Peripheral or Central and Client or Server.User Can Create up to Five Public and Four Private Services.GAP, GATT, SM, L2CAP and Integrated Public Profiles.The The RN48709/1 has full BLE 4.2 functionality: This can be considered a serial cable replacement, however, if this is all you need you may be better suited with the HM-05/06 or HM-10.

The UART Transparent Service for Serial Data allows an easy way to link 2 modules together. This means, depending on what you want to do, you may not need a MCU like the Arduino, the RN48709/1 can be used stand alone. It also has a mini programming or scripting language built in. The main difference s that the The RN48709/1 has it’s own set of unique commands and does not use AT style commands. The RN48709/1 is configured using ascii commands similar to other BT modules.
