Hi, I have set the `dio_0` pin number in `config.py` and changed the code in `examples/LoRaReceiver.py` as following: ``` def receive(lora): print('LoRa Receiver Callback') def cb(payload): lora.blink_led() print(payload) lora.on_receive(cb) lora.receive()...

Is there anything specific that needs to be configured in order to receive data via. LoRaWAN and TTN ? Neither the callback function or any related methods in the sx127x...

Hi, have a "Sparkfun ESP32 Lora (WRL 15006)" board. MicroPython is running on it. Tried to make "device_config" section in "config.py" with informations from this [schematic](https://github.com/sparkfun/ESP32_LoRa_1Ch_Gateway/blob/master/Documentation/LoRa_Gateway_1-Channel_Schematic.pdf). device_config = { 'miso':14,...

Hello, I'm using your code on the TTGO LORA 868. It works, great job! anyway in my main.py I wanted to use a machine.deepsleep() to optimize the current consumption when...

We have detected and MIC error while sending 7 or 23 bytes (whenever we calculate the MIC of a 16 bytes packet, so header 9 +7 = 16, 9+23 =...

lora_parameters = { 'tx_power_level': 2, 'signal_bandwidth': 'SF7BW125', 'spreading_factor': 7, 'coding_rate': 5, 'sync_word': 0x34, 'implicit_header': False, 'preamble_length': 8, 'enable_CRC': False, 'invert_IQ': False, } Do you have cfg to AU915, BRAZIL ?

Perhaps you can document some of the lora_parameters. I had to set enable_CRC:true for it to work. Otherwise a great job!

…elf._lock is true While using the uPyLoRaWAN with an asynchronous web server, [MicroWebSrv2](https://github.com/jczic/MicroWebSrv2), I noticed that my Tx data was being corrupted which I believe is due to `received_packet` resetting...

Hi, thank you for your code. I'm using a TTGO ESP32 SX1276 Lora 868 [ali express](https://nl.aliexpress.com/item/4000059708434.html?spm=a2g0s.9042311.0.0.27424c4dM50j5d) ``` parameters = { 'tx_power_level': 2, 'signal_bandwidth': 'SF7BW125', 'spreading_factor': 7, 'coding_rate': 5, 'sync_word': 0x34,...

Fix for `println` method which fails when sending anything else than string. (+ format with `black`)
