## Known limitations

16+
### [v1.1.9]
17+
18+
#### Index values for file upload initialization command (present since v1.0.7)
19+
20+
Only index values from 1 to 223 are allowed.
21+
22+
#### Power emission for ARIB (present since v1.1.7)
23+
24+
For ARIB, power emission must be typically set to 9dBm by setting the power offset during the JOIN procedure using SetTxPowerOffset command during the device configuration phase after Reset as explained in the Reference Manual documentation.
25+
26+
#### FPort value when using the stream service (present since v1.0.7)
27+
28+
The parameter `FPort = 0` (i.e. put the stream in a DM frame) can lead to an undefined behavior of the stream service and must not be used. Make sure you explicitly use the DM FPort value if you want to send a stream as a DM frame. This limitation is also impacting previous version of the firmware.
29+
30+
#### File upload service with encryption mode enabled (present since v1.0.7)
31+
32+
The file upload service cannot be used with encryption mode enabled. If data encryption in required, the user has to encrypt the file at the application level and then send it through the file upload service.
33+
34+
#### Number of retransmission (present since v1.0.7)
35+
36+
The number of retransmission cannot be set greater than 7. If value higher than 7 is required, it is recommended to retransmit the packet at the application level. For instance, if an overall number of retransmission of 13 is required, the user has to send two packets with the number of retransmission set to 8.
37+
38+
#### Constellation to scan after a partial GNSS almanac update (present since v1.0.7)
39+
40+
A partial GNSS almanac update will modify the constellation to scan parameter. As a workaround, the user has to reconfigure this parameter just before launching a GNSS scan.
41+
42+
#### ADR fallback with uplink dwell time activated (present since v1.1.7)
43+
44+
For AS923 and AU915 regions, the ADR fallback is equal to DR1 or DR0 when the uplink dwell time is activated: the modem cannot send uplink frames anymore.
45+
46+
#### Modem crash in region RU864 (present since v1.1.7)
47+
48+
When receiving a NewChannelReq MAC command in RU864 region, the modem crashes.
49+

# LoRa Basics Modem-E v2 firmware
2+
3+
LoRa Basics Modem-E offers seamless embedding of the LoRaWAN stack into LR1121 chip. Once flashed on the LR1121, the binary code of Modem-E offers:
4+
5+
- Fully featured stack with all classes (A/B/C)
6+
- all regional parameters and WW2G4
7+
- CSMA/LBT
8+
- Relayed end-device (i.e. Relay Tx)
9+
- Multicast class B/C
10+
- FUOTA (one fragmentation session is supported)
11+
- The possibility to co-host on the same sensor LoRaWAN and proprietary protocol leveraging state of the art RF performances of LR1121.
12+
13+
## Driver version
14+
15+
The driver for this firmware is available here [https://github.com/Lora-net/lr1121_modemE_driver](https://github.com/Lora-net/lr1121_modemE_driver).
16+
17+
| Firmware | Driver to be used |
18+
| -------- | ----------------------------------------------------------------------------- |
19+
| v2.0.1 | [v1.0.0](https://github.com/Lora-net/lr1121_modemE_driver/releases/tag/v1.0.0) |
20+
21+
## Known limitations
22+
23+
### [v2.0.1]
24+
25+
#### Transceiver mode
26+
27+
When used in Transceiver (Suspend) mode, the chip might get stuck in Sleep mode if SetSleep command is called with RTC mode set to 0 (XTAL) and no timeout is set.
28+
29+
Workaround:
30+
31+
If running any application with Modem-e in TRX mode (for legacy protocols), make sure that ${\textsf{\color{red} SetSleep() command is used with RTC mode set to 1 and a timeout is set.}}$
32+
33+
Note that the existing transceiver driver contains this workaround
34+
35+
#### FUOTA
36+
37+
A single fragmentation session is supported. Fragmented Data Block, frag_index must be set to 0
38+
39+
#### LoRaWAN
40+
41+
#### TxParamSetupReq only active after LinkADRReq
42+
43+
MaxEIRP requested by the MAC command TxParamSetupReq will only be applied after the LinkAdrReq is received. LinkAdrReq must set power between 0x0 and 0xE.. This only affects AS923, AU915 and WW2G4 regions.
44+
45+
Workaround : make sure that the LNS sends LinkAdrReq (with power set between 0x0 and 0xE) right after TxParamSetupReq to operate with the proper power level.
46+
47+
#### LinkADRReq behavior with network ADR disabled
48+
49+
When the modem-E is configured with network ADR disabled, and receives a LinkADRReq from the network nonetheless, the modem will accept it and apply the included ChMask, but it will refuse the power and the datarate settings even if the value is 0xF (in normal case 0xF should be accepted). It should discard the entire command but does not.
50+
51+
Workaround: Modem-e is NOT expecting to receive LinkADRReq when it is declaring itself as ADR disabled. Make sure the LNS behaves accordingly.
52+
53+
#### Join Data Rate distribution might erroneously be used for normal traffic after Join
54+
55+
The modem keeps the JoinDatarate distribution after it has joined in two cases:
56+
57+
- when the CSMA or LBT detect a possible collision during the first joinReq
58+
- when the user leaves before the end of a join attempt, then tries to join again
59+
60+
Workaround: On Join success Event set your ADR profile systematically
61+
62+
#### Get regional duty-cycle
63+
64+
For region with duty-cycle constraint, if transmit time is available and the Relay Tx is disabled, the function to get the duty-cycle status return 0 instead of available time
65+
66+
#### Modem-e at 2.4GHz
67+
68+
In modem mode with 2.4GHz path the -18dBm is not usable, if used it will result in undetermined behavior
69+
70+
Workaround: ensure that the LNS doesn’t request -18 dBm output power.
