Release notes: 2020-03-04
Firmware package: RAK7200_Latest_Firmware.zip for EU868/US915/AU915/KR920/IN865/AS923 regions.
Firmware Version: V3.X.0.12
BOOT Version: V3.1.1
Feature:
1.Add “gps,voltage,acceleration,magnetic,gyroscope” parameters open/close AT command.
You can use “at+help” command to see more details.
2.Fix the issue about saving the configuration of sensor.
3.Add a method about subcontract when the length of the packet is bigger than the current max payload
Currently under test and need to say it works fine at my site!
Thanks RAK

Firmware package: RAK7200_Latest_Firmware.zip for EU868/US915/AU915/KR920/IN865/AS923 regions.
Firmware Version: V3.X.0.13
BOOT Version: V3.1.1
Feature:
1.delete LoRaP2P AT command because RAK7200 don’t support LoRaP2P mode
On the RAK-homepage (and Reichelt too) the RAK 7200 is still offered with a barometric sensor. But there is none. Could it be possible to install an additional sensor like BMP380?
The docs show a block diagram with a MPU9250 - a fairly typical module - how good do you need it to be, the datasheet will probably give the info you need.
I am on the current firmware. The device is next to the window, but I do not get any GPS data. I set the GPS timeout to 180 seconds already. Has someone any suggestions?
Maybe a few additional details:
>>at+version
OK3.1.0.13
>>at+get_config=device:status
OK.

and when it comes to viewing the current GPS data:
FAIL.The Satellite signal not found!
Also, after looking in the at+help I need some help. Is there a way to get a further description of the commands? Something like man man just with at+help…?
thank you, directly under the sky it did work. Though I cannot say that I am satisfied with the solution. I wanted to put the tracker into a wooden sailing boat. Do you think it will come through a bit of pine?
I opened the box up to check for an antenna and noticed that there is none except the chip. Would it be worth trying adding one? Do you have any recommandations or even manuals?
Thanks a lot again for the quick response. For now it works so I can stop for today.
GPSs have to work with very weak signals, so may not work well indoors, next to windows, or in thick boxes. The only way to find out is to try, you have the GPS after all.
I doubt the GPS has no antenna, it would be unlikely to work without one and neither have I ever seen the inside of a RAK Tracker.
I dont have a 7200 but previous gen 5205’s shipped with both LoRa and and GPS Ants on short pig-tails (u.fl or SMA options were available) suspect image just shows lozenge placement…still using pigtail connection?
If you’re doing that all day long, then even when sending only 1 byte of application payload (hence 14 bytes for the full LoRaWAN packet), on the fastest data rate, TTN will only allow for 2 messages per minute.
