Change to nRF52833 module? Introduce What the Hardware & Firmware Perspective Need To Review!

Developer who currently are using nRF52840 based modules must be excited waiting for nRF52833’s distribution. Most developers are aware that nRF52833 supports long range, multi protocol and USB interface but has less RAM and Flash memory rather than nRF52840 and no doubt is the best alternative to have cost effective without extra efforts.

Raytac has released 3 models of nRF52833 based modules just at the same time when Nordic released, MDBT50Q-512K / MDBT50Q-P512K / MDBT50Q-U512K. Both nRF52840 and nRF52833 module are based on same form factor and pin out. To have quick visual identification finding the difference, Raytac’s nRF52833 modules are built by Green PCB but nRF52840 modules are Blue.

Raytac Jointed Apple HomeKit MFi Program

Standing on marketing perspective point of view, iPhone user are often been viewed as a higher contribution margin group. Not only talking about consumer behavior, but also the motivation looking for device integrated with their own iOS devices. That explains why HomeKit devices recently has been widely spreading out in Apple stores or shops.

Wireless technology, says Bluetooth or WiFi, is the key role to connect between devices for Apple HomeKit implements. Surely, Bluetooth is more applicable than WiFi, not only easier to connect to iOS devices but also much lower power consumption and higher security level to rich consumer’s experience.

Raytac has been devoting to Bluetooth Low Energy module development for several years, started from BT4.0 to the latest. Raytac modules has selected Nordic’s solution, which is a highly optimized solution running HomeKit Accessory Protocol (HAP) and application firmware. The ultra-low power even enhance the design and usability for HomeKit devices implements.

After MFi Licenses program jointed, Nordic nRF5 HomeKit SDK is capable to access, Raytac expects to escalate the support ability in terms of hardware and firmware aspects for all customers who are interested in Apple HomeKit implements.

nRF52840 v.2 – What’s New?

From IC Revision 1 to 2While there are quite a few changes available for review in the nRF52840 documentation, there is update that is particularly important for many users out there, including a large amount of our own customers. The update I am talking about is about the power supply.

First things first – if you’re interested in reading the whole documentation for Nordic Semiconductor’s nRF52840, then look no further than their Infocenter.
nRF52840 IC reversions and variants

As you can see in the picture below, there’s a lot of information about LDO and DC/DC regulators. That is exactly the main topic of today’s post.
On nRF52840 version C, when changing from 5.5V to 3.3V, you had to use LDO mode in order for the chip to function properly. In the new chip version 2, you won’t have to change to LDO mode as you can directly use REG0 DC to DC.

I will let the Infocenter documentation speak for how it works in detail as quoted below:
Nordic Infocenter - nRF52840 Power Supply update.PNG

The system contains two main supply regulator stages, REG0 and REG1.

Each regulator stage has the following regulator type options:

Low-dropout regulator (LDO)
Buck regulator (DC/DC)
In normal voltage mode, only the REG1 regulator stage is used and the REG0 stage is automatically disabled. In high voltage mode, both regulator stages (REG0 and REG1) are used. The output voltage of REG0 can be configured in register REGOUT0. This output voltage is connected to VDD and is the input voltage to REG1.

By default, the LDO regulators are enabled and the DC/DC regulators are disabled. Registers DCDCEN0 and DCDCEN are used to independently enable the DC/DC regulators for the two stages (REG0 and REG1 respectively).

When a DC/DC converter is enabled, the LDO for the corresponding regulator stage will be disabled. External LC filters must be connected for each of the DC/DC regulators being used. The advantage of using a DC/DC regulator is that the overall power consumption is normally reduced as the efficiency of such a regulator is higher than that of a LDO. The efficiency benefit of using a DC/DC regulator becomes particularly prominent when the regulator voltage drop (difference between input and output voltage) is high. The efficiency of internal regulators vary with the supply voltage and the current drawn from the regulators.

Note: Do not enable DC/DC regulator without an external LC filter being connected as this will inhibit device operation, including debug access, until an LC filter is connected.

We hope you get a better understanding about the update from nRF52840 Revision 1 to 2 and its power supply.

Raytac now has started supply module demo board, MDBT50Q-DB, build by nRF52840 v2 SoC.

If you would like to purchase our MDBT50Q-DB demo board (deployed module: MDBT50Q-1MV2) on it, you can get one on eBay or Verical.

We at Raytac wish you all a nice day and happy tinkering 🙂

Raytac’s UART Service (AT Command) – How do you get started?

Easy! At least when you know what to doMany of our customers just want a device that provides Bluetooth technology to their product or solution that they’ve developed. However, utilizing the full capacity of the Bluetooth protocol is not always easy and sometimes not even necessary. For these customers, choosing Raytac’s modules/dongles loaded with AT Command, such as MDBT50Q-RX-ATM, is the best choice.
But even a product such as MDBT50Q-RX-ATM that is supposed to make it easy for customers to wirelessly transfer data from one device to the next can be difficult to use – especially when you don’t know HOW.

So, I thought we’d take this in two simple steps.

  1. Device Name

To be really sure that you can connect to the device thus making you able to pair with it, you will have to make sure that the device name setting in the AT Command list is set to the name you want or need.
For example, if you have a device set to have the name “I_love_Bluetooth” and you haven’t changed the settings in the AT Command, you will not be able to pair your MDBT50Q-RX-ATM with this device.
As you can see in the picture below, the default setting for this device’s name is “Raytac AT-UART”.

When editing this name, you get a smaller window like this popping up:

Make sure that the name set on your device that you wish to connect with the dongle AND this name in the AT-Command device’s list are the same.

  1. RSSI

This is a trickier part – especially when you don’t know what it is.
RSSI stands for Received Signal Strength Indicator and, just like the name implies, is a value of strength of which the incoming signal has to be in order to even be considered by the scanning device.
In other words, the lower the value is set to, the weaker signals the scanning device will show.
The standard value of Raytac’s AT-Command modules/dongle is -51 and the setting screen looks like this:

  1. Slave device’s SDK

What many new customers seem to believe is that if you use our AT-Command modules/dongles, you won’t need to do anything – they will just magically communicate with each other somehow.
I hate to break it to you, but no… that’s not how it works. You will have to at least make sure that the two devices “speak the same language”. As for our AT-Command modules/dongles, or in this case MDBT50Q-RX-ATM, it is through a “language” (a.k.a. protocol) called UART.
First of all, “UART” is not “U-ART” although it’s kind of pronounced that way, but it’s an abbreviation that stands for Universal Asynchronous Receiver/Transmitter. You can read about it here.
I will spare you all the details about the UART protocol itself, but one thing that we will need to make sure of is that you have it installed onto your slave device.

Hopefully, you’ve downloaded Nordic’s latest SDK and you have it ready on your computer. You can download them directly HERE.
Note: This file is quite big (~130MB), so DO NOT click on the last link if you don’t want to download this on your current device.

Inside this file, you will find a lot of stuff. However, for this particular case, we only really need to care about the “examples” folder.

In this folder, we will have (surprise surprise!) even more folders 😀
As per usual, we don’t have to check them all out. In this case, we specifically only want to check the “ble_peripheral” and the “peripheral” folders.

Go into the former folder and you’ll find see the following folders in which you will want to enter the “ble_app_uart” folder.:

In this folder, you will see five more folders and two files, but we only want to check out one of them depending on which chip type you’re using in your slave device. Let’s say you’re using a nRF52832 chip (or module such as MDBT42Q-P512KV2), then you’d want to enter the first folder called pca10040. Check the picture below to see which folder you’d want to enter:

Assuming you entered the folder that I mentioned above, you will then want to enter the “s132” folder.

Once you’re in here, I am pretty sure you developers out there know what to pick 🙂

In the beginning of this section, however, I also mentioned another folder called “peripheral” which we will guide you through now – even if it’s very similar to what we just did.

As you can see, there are a TON of folders in here, but we will cherry-pick our folders here too.
Let’s say that you’d like to be able to make your slave device to read and transmit information from a sensor. Supposedly, most sensors use either the I2C or the SPI interface. In each respective folder, you will find the same folder layout as in the previous picture – folders representing what chip/module you have.
The main point of showing you this is simply because from these two folders, you can snatch the small amount of code that you need to edit the main code of your UART main-code so that you can both read and send the data from the sensor you might have.

Hopefully, you’ve now started to realize how these things come together and we can finally start to connect these devices. This takes us to the next step:

  1. ATSCANNEW

Once that’s done, you will need to use your AT-Command module/dongle (here MDBT50Q-RX-ATM) to scan for the slave device that you want to pair. To do this, you first have to make sure your slave device is broadcasting, then execute a command called ATSCANNEW.
Once you’ve done so, your MDBT50Q-RX-ATM’s blue LED will hopefully go from fast blinking to a slower blinking. This means that your two devices, master and slave, have now paired successfully. Wohoo! 🙂

We hope that this makes our AT-Command modules/dongles even easier to use!
Raytac wishes you all happy tinkering 🙂
