@juan_peroza JSON is not a protocol, it’s just a data representation. You can send whatever you want, but JSON is not very space efficient, and is usually not the best choice for data sent over a (very) low bandwidth link such as LoRa, SigFox, NB-IoT, or BLE. It’s usually better to use an optimised binary format in those cases.

Hi @klaus, Currently, you can only configure one WiFi network, and save multiple in the Pybytes console.

@paul-thornton I got that sorted by modifying line 53 in urequests as per a suggestion I found online somewhere Paul. I could really use some help withhttps://forum.pycom.io/topic/4014/gpy-in-deep-sleep though.

@jimpower ok, so why do you get no module found when you call urequests.post now when you didn't before. I can't see all your code, just snippets. The vaious sample bits of code are being changed. Oh I see now what the problem is, when you import urequests you are importing as requests hence the module not found error. You will need to change the sample to requests.post Also as an aside why do you execfile('/flash/Wi-Fi/Wi-Fi.py') rather than importing. This seems odd thing to do.

@smbunn It's probably much easier if you use a single pack with a single format string and all the values you want to pack in there. Otherwise you'll end up with issues of incorrect offsets or lengths at some point when you'll edit formats.

@livius I added tmp = uart1.readall() and it works thanks again I managed to do this before your reply thanks again you are always very helpful

@livius Thanks for your help, the gc.collect() has worked and the loop has remained stable for a few hours now.
