RE: Is RAK811-Tracker Boards DEVEUI all the same?
@ogahara the deveui is unique for each device; if you can use a private network like ttn...probably they give to you a unique devEui for to one physical device (you can't asign any devEui that you like it). If you deploy your private network, you can asign to your devices the devEui that you prefeer, like: "0000000000000001".

RE: RAK811/LoRa Module Latest information summary
I have some question about the power supply and current consumption of RAK811 module (sx1276 module + stm32l151). The datasheet "RAK811 Lora Module Datasheet V1.1" explain on the "Recommended Operating Rating" for VCC are: 3.15 V(min), 3.3V (typical) and 3.45 V(maximun); for the "Current Consumption" only the minimum consumption are descripted: 30 mA(14dbm) (tx mode), 5.5 mA (rx mode) and 7.2 uA (sleep mode) . For the other hand, the brochure of rak811 "RAK811_Brochure(V1.0).pdf" indicates TX: 60mA; RX: 9.9mA; Sleep: 500nA, with no identification of max, min, or tipic values. Wich really are the values min, tipic and maximun for RAK811? The documentation looks like some confuse to me.
About the power consumption, sx1276 can work with 3.7V and stml151 with 4V of maximun values. Why rak811 does can't work with 3,7 v (the minimun value of the maximum vcc of this two chips)?
The rak811 module have a regulator inside?
We must be know this values for comercial products.
RE: RAK811 Tracker - HowTo
@xc.c HI! I am really new on the stm32 enviroment, but i know on the arduino ide you can use some digital pins for create a virtual serial interface (and you can use ftdi for comunicate with PC). I can do this with stm32 (keil uvision) enviroment?
For your suggestions can i write:
1-The recomended desing fot texas for the switch is; correct for your apreciation: R1/C1 connecte to Vin.
2- for the Power indicator LED1 light you can maybe put a jumper for desingn uses and we can remove the jumper on production enviroment. The reverse charge indicator and two gpio control status are very ussefull.
3-The ublox gps drink to much current, if you indication is possible; we are thinking on buy alot of rak modules.
4-For productions cases we dont use the usb module, only use for charging propose with a solar charger.
5-I don't any example of this use, maybe it be very ussefull. I m only use the voltaje level of battery.
6-A better antenna for us915 mhz.
