@jcaron I update firmware of modem same as existing one then problem solved. now can communicate.

@ahmadelmasri Thanks so much! I can log in again!

@robert-hh I changed P8 to P9 and it works great! Thank you so much!

@melkoutch hope you still read this as this thread is quite old. I stumbled upon it having the exact same problem (LoPy4 <-> Feather M0 in raw LoRa). Adjusting the spreading factor doesn't seem to solve it for me. Would you be able to post the code fragment that you used to successfully connect the two? Thanks a lot!

In my opinion RESET pin should not be left floating. Try to connect pull-up resistor to 3.3V in 10k-20k range. Check L01 OEM Baseboard schematic: https://docs.pycom.io/product-info-datasheets/oem/l01_reference Edit: Sorry, now I noticed the reset pull-up already being in your schematic. Anyway try to use FTP client for script uploading.

@robert-hh Thanks, I am working on a very small laptop so I didn't see that as it wasn't very obvious :-)

@tom You should probably instead do the following set socket to blocking send set socket to non-blocking receive save config Otherwise you actually try to receive, save, and deep sleep before the packet has actually been (completely) sent. An alternative is to add a manual sleep, but remember that the time between send and receive is variable (the network can change the RxDelay).

For a Pytrack Pytrack().read_fw_version() works, but I don't know how to do that for the expansion board.

The most pressing item is just how do I identify the client that is connecting to the GPy over BLE? Typically a BLE radio will give a MAC address and a connection handle to be able to manage the connection. I am not seeing anything in the docs that addresses this.

@cclawton Please download the latest library inside Pybytes, there have been some updates to the main.py It is also recommended that, when working with the Pybytes firmware, you start with the main.py_example1 file in the flash/examples directory instead of the full main.py

Could you guy provide resolution to above error please ?

@tushar44 Are you running an upto date version of pymakr? The ability to copy from the terminal was added quite a while ago

@Mohsen-Paryavi did you have any luck getting this to work? I'm interest in doing the same, using the Gpy as a LTE Cat-m1 hotspot. Allowing a phone to wifi-call beyond LTE coverage.

Tried two cables. Same result. One green flash. Nothing after that.

Aha, LoPy 1.7.8-b1 micropython 1.8.6-724 loran 1.0.0 Alright I'm going to update the lot. Maybe some hints in the doc like micropython does with the different versions....
