would you please tell me about your plan for these problems?
Are you going to release a new Firmware? or we should start to develop our Firmware?

RE: New Serious Problems with RAK811
Sure, I'm using the latest firmware (firmware V188.8.131.52) from RAK github.
below is the link of firmware:
New Serious Problems with RAK811
We recently used RAK811 module in some sensor nodes and it should send data twice a day. It's clear that we operate RAK811 in class A. After these tests, we found many problems in RAK811 operation that would make it useless.
*1:In OTAA join to network, module "always" use SF7 to join network which is not true, refer to LoRaWAN Specifications. It would be better to use SF 12 to have a more "reliable Join".
*2:Module should optimize it's "Data Rate" after join response! It's part of LoRaWAN Spec. and module just use SF 12 with its last firmware V2030.
*3:Some times after exit from Sleep mode, Module will not send any data. It receives command to send data whether with or without ack, then response with "OK", but "at+recv=1,0,0" response with appear about 1-3 minutes later!!! We don't know what is the problem. This is the most important problem, because it will increase power consumption significantly.
*4:Other problem is about "AT Command" interface. It's better to receive a response like "Busy" when it's LoRaMAC is trying to do something like join or send. For now, user will not know the situation and cannot do anything else but waiting for response.
We are studying RAK811 to find other possible problems, but it will be greatly appreciated if RAKWireless support team release a new firmware to solve this problems.
