Disabling ADR in SAMR34 with MBedOS when OTAA method is used

Govardhan1999 commented 4 years ago

When using MBedOS in SAMR34 Xplained Pro with the following LoRa configuration I am facing the issue with disabling ADR in OTAA method and setting the desired Data Rate for LoRa Transmissions

Configuration used::

Transmission Type : OTAA
ADR : Disabled
Data Rate : Set to DR_0
Delay B/W Transmissions : 0
Frequency Band : IN865
Payload Size : 10Bytes
N/W server : Chirp Stack (ADR is disabled in N/W server-side)

Observations we got::

Uplinks packets are received with DR_5 even we set DR_0
When used ABP method ADR is disabled and uplinks are received at DR_0 as expected

How can we address this issue of disabling ADR in the OTAA method

Thank you for the references

Observations I got after implementation

The join requests are happening at SF7-SF12
After the connection is done the uplinks are sent at the data rate set in the connected event handler
