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.
@rop 在 M5 Fire and the IMU 中说：
It really sucks that the people making these things never answer any questions...
You named it ... These are so exiting devices, but if you study the docs I have to facepalm my self sometimes :-)
Thx for the link to your repo. Unfortunately I don´t have a fire yet. I ordered a black one (where I didn´t know that the IMU is not available). And then I ordered a gray one. It took 4 weeks to get the gray one to germany. I know it has arrived some days ago but I´m on vecation until saturday :-)
The black one is still missing - for 5 weeks now. I really hope it arrives, soon.
So I will do my first tests on saturday or sunday. And I´m still unsure if I should order a fire. Is it worth the price ... and did I really need the additional features?
I´m working on a data glove at the moment where I will use the gray M5Stack - or let´s say I hope I can use the M5 in general. I hope it´s not to heavy and I can mount it on top of the glove. But that´s a little bit OT now ...
Will see if I order a fire for some detailed testing :-)
@watson 在 M5camera supply. 中说：
Yes, it is. But be careful that you must ensure the supply of USB and GROVE must be common-ground and the supply can not be too high. Otherwise, the power chip of M5Camera will be burnt.
Ah, there in lies the problem,
I was going to use the USB to draw power from the laptop and the Grove to draw power from an auxiliary battery pack.
MKII (PSRAM) camera
Standby = 0.1A
connected = 0.14A 00592mah
Running a lot cooler then the MKI
I don't have anything else to test so that's all I can give.
Measurements taken with a Keweisi branded usb test meter.
Look in your "downloads folder" (where ever you download files to)
You should see a strange file. When you open the file, there will be captured images in it.
I'm waiting on my MK2 camera (WROVER) to arrive to see what the difference in the 2 are.
Yes, i have the same problem under win 8.1 64bit version. when including the file
http://www.m5stack.com/support/master/package_m5stack_index.json and trying to include this, an error message occurs: http://www.m5stack.com/support/master/package_m5stack_index.json Dateisignaturprüfung fehlgeschlagen. Datei ignoriert. Under win 8.1 64 bit vers. it is not possible to ignore the file verification.
@stoney 在 Have the camera, what now. 中说：
Does not work
Then next post you say it works ? You are being confusing lol, you can edit the posts if you want..
Nope it doesn't work however, reading the source code that you linked to and a bit of probing, I found the other info but mine seems to have overheated and died.
I need to find someone to solder in some wires to bypass the usb>usart chip and I just cant get it to work.
Is it supposed to only draw 0.1A?
Just trying to work out why the esp32 is running hot.
