This is my first post in this forum. I used the search but could not find a solution for my problem.
I would like to read the tx power level of BLE beacons with my M5Stack ESP32.
I get the rssi value but I would like to know the transmission power. I do not mean the 1Byte "transmitted/measured power" that you should receive on 1m range. I mean the power level that determines how strongly the beacon sends its broadcast (what the max. range should be).
I would like to read whether the beacon is configurated to send only at e.g. max. range of 2m or maybe 15m.
I use Arduino and PlatformIO with int8_t BLEAdvertisedDevice::getTXPower ()
And I always get txPower: 0. using haveTXPower() returns false. But my smartphone with the usuals apps displays without and problems the txPower value (e.g. -20dBm that would indicate the ble beacon has only few meters max. range)
Did anyone had success with a M5Stack to read those txPower values?
Is there any code snippet that REALLY WORKS? There are planty online but they show 0 txPower and false on haveTxPower.
edit: further infos from platformIO
PLATFORM: Espressif 32 > M5Stack Core ESP32
HARDWARE: ESP32 240MHz 320KB RAM (4MB Flash)
Libs: M5Stack 0.2.5
Hi I certainly did it, ampy is installed and functional but doesn’t seem to connect to the device.
Thanks for looking into this. Removing all unnecessary beeps from the standard firmware would be great. No-one would buy a car honking at every steering or dashboard switch activation!
@lukasmaximus said in BTC 2.0 not powering the basic M5Stack:
@gadjet sorry this was definitely an issue with the description. The btc ticker is not capable of charging the m5 stack.
I wouldn't mind but I bought two of them !!! Oh well back to my 3D printed stand and a big battery.
I would like to request that color is defined in the blocks in a way that allows the user to select one of 2 color block options
you can add color by using a general color swatch selector like you have currently on most blocks
you can add an RGB block that allows color to be treated as variables.
I feel like these two color options should be broken out as two color blocks that can be added onto the blocks as needed. Currently you have color broken out as three variables in some of the ui blocks but in none of the graphics blocks and this is limiting. What I am suggesting is all tools requiring color require the user to add on a color block and the color block can be one of these two types (color swatch, or RGB variables). I think this can help make the interface cleaner since you don't have to have all these redundant blocks but rather a single block with the option to select how color is to be defined. This gives the user way more programming options since they can opt to use a swatch when needed or to use RGB number values or variables if needed.
Also I think you need a list block to define the length of an array. It would also be great to have a block for list pop.
@watson 在 Arducam (arduino) Can't find OV2640 module! 中说：
Here's the pinmap about camera supplied by m5stack.
That doesn't tie up because the arducams arduino_pin.h has D2 as I/O12
and slave select as I/O17
Not with the Adafruit-GFX library that is the display driver in the M5Stack library. You can rotate the display, but only the whole display, not show text in multiple orientations at the same time.
It would be a cool modification though...
@watson 在 A few questions about the stepper motor model. 中说：
A1 here is the document and picture about stepmotor module
A2 Yes, soldered to PCB
Thanks, I wondered why I could not move them or find the atmega.
@lukasmaximus 在 MicroPython lcd.qrcode is not work 中说：
Thank you for your reply!
By your explanation, I understand that there is a difference between the two services.
I was thinking of using M5 Cloud Offline to use M5 Stack offline.
I usually use Python, so I wanted to use microPython.
However, given the richness of the library, I felt it should be implemented with cpp.
In the future, if microPython 's functions are enhanced, I would like to try again.
Hi My Friend,
You mean the rubber pad as below photo ? But sending these only may needs a high shipping fee. If you have any plan to make a new order our AliExpress store, can leave us a message. I'll send you some for free together.
@loboris 在 X-Code on OSX intergration. 中说：
esp-idf has been available under OSX from the beginning.
Standard Setup of Toolchain for Mac OS
Yes I know that but there is no intergration with osx'x native x-code ide.
