Has there been any resolution to this? I have the same problem with all my 4 Pycom circuits - I have both GPy and WiPy circuits and Expansion board 3.0. It happens even if there is no program loaded. It happens with or without the Expansion board. If I cover the circuit in my hand, it does not happen. If I remove my hand, it starts core dumping again. So it has to be an electrical problem of some kind.
I have the same opinion as @jcaron . MTU size is something that has to be configurable. We should be able to set MTU size of Pycom. Changing is not going to break anything in case of good implementation (I've already tried it with Pycom).
@Emmanuel-Florent the reason I've started this topic is that I've experience with ESP32-DevKitC and BLE MTU size changing, on that size everything worked fine, so I'm just requesting the same functionality on Pycom if possible.
Reading in the things networks forums, there is some interesting material about work regarding firmware updates using LoRa.
Let's say for example the things network implements over the air updates via lora in their console. Could existing LoPy's (4) use this feature, or could a manual firmware update from pycom enable this feature or not possible?
We have user's who have implemented there own firmware OTA using lora in the past. I dont think anything got released for public use however. Ill try and find out what our plans are Re: Lora OTA.
You can specify the Lora region via the Lora() constructor in your code instead. I believe (but will have to confirm) that the drop down setting it only used when dealing with pybytes. I will confirm this however.
@martinnn If you build the firmware from the sources you get the most recent version. These numers are in the file pycom_version.h. At the moment it tells 1.18.2.
Revision tags are not added often to the repository. So you see just a few of them.
@jcaron Yes, and it works!
Now I am trying to figure out where to put my module.
In the ESP8266 version there is a file called ESP8266.ld which contains the list of C files.
Where is the equivalent for ESP32? If there is no equivalent, what shall I look for?
