Re: esp32-idf parttool.py stops with error UnicodeDecodeError (IDF-2839)
As an additional info: I've run the same test after installing the pre-requisites and the esp-idf dev stack on a ubuntu docker image. Got the same error message.

Re: esp32-idf parttool.py stops with error UnicodeDecodeError
Hi Roland,
Thx for the reply. Following your suggestion I've created a minimal key-value pair for nvs:
filename: test.csv
content:
key,type,encoding,value
default,namespace,,
key1,data,u8,1
I converted it to binary first, using:
nvs_partition_gen.py generate test.csv test.bin 0x80000.
and ...

esp32-idf parttool.py stops with error UnicodeDecodeError (IDF-2839)
HI,
I've run out of ideas on this one and now my project is stuck - really appreciate if someone can help on this one.
When running parttool.py to upload a .bin nvs file I get "UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 1: ordinal not in range(128)"
I am using esp-idf ...

The Things Network + RF96 - which library to use ?
Hi,
I am looking for recommendations on libraries to connect to TTN using lora transceiver RF96.
I've managed to connect successfully using SX1276 + ttn-esp32 library. Unfortunately the same library seems not to work when using RF96. (I've banged my head for 2 days without success).
Which ...

Sleep time drift due to temperature when using ULP/ulp_set_wakeup_period()
I am experiencing a sleep time drift/error when using ULP wakeup under different temperatures.
I am calling:
ulp_set_wakeup_period(900000000) // 15 minutes
Situation1:
- ESP32 Wroom 32E runs on ~23 degrees Celsius, I see the wake up happening about 2 seconds earlier than the 15 minutes. For me ...

GPIO25 as PWM output connected to GPIO33 as ADC input - voltage drop on pulse
I am a bit stuck on this one and would appreciate help or tips from the community here...
I am using ESP-IDF and using a dev board from TTGO (with LORA).
I've programmed the GPIO 25 to have a 100KHz PWM output with 50% duty cycle.
Looking at the osciloscope I see a nice, well behaved pulse 0-3.3V ...

ESP32 inconsistent readings on GPIO D33/D32
Hi Experts,
I cannot get this right, so thought about asking for help here...
I have an ESP32 DOIT dev board with D32, D33 used in input mode as follows:
On D32 I have a temp sensor (D18B20).
On D33 I use a voltage divider (1MOhm, 1.32MOhm) to allow me to read the voltage on a source of ~5.6V ...
