Miner version is not sent to the mining pool

[PSLLSP]

I updated my miner with firmware v1.6.3 but hashrate is still only about 55 kHps. This is for miner TTGO TDISPLAY v1.14. So, I am not sure if the miner was really updated to version 1.6.3 or if hashrate is "low" only because it has different CPU and it cannot hash at 78 kHps...

I cannot find any information about firmware flashed to the device, it is possible that WebFlasher updated device with older firmware, like v1.6.2 or v1.6.1. Unfortunately, I cannot see firmware version on display or on console, it is not send to the pool. Some pools can show miner version (Zergpool, MiningRigRentals), other could use it for statistical analysis or for troubleshooting... It is possible that once NerdMiner will report version to the mining pool, that even public-pool.io can use it and show firmware version in the miner detail...

I open this issue because I believe that miner should send firmware version to the mining pool. This is what I see in the serial console, only miner name is there, but no firmware version:

Sending  : {"id": 1, "method": "mining.subscribe", "params": ["NerdMinerV2"]}

This is cpuminer, it sends version to the pool (use parameter -P to see protocol details):

[2023-11-30 00:02:23] > {"id": 1, "method": "mining.subscribe", "params": ["cpuminer/2.5.1"]}

cpuminer-opt sends this:

[2023-11-30 00:39:05] > {"id": 1, "method": "mining.subscribe", "params": ["cpuminer-opt-23.14-x64L"]}

cpuminer-rplant reports this:

[2023-11-30 00:44:26] > {"id": 1, "method": "mining.subscribe", "params": ["cpuminer-rplant/5.0.36L-avx"]}

ckpool running in proxy mode reports version ckpool/0.9.5

Please, change parameter mining.subscribe call from NerdMinerV2 to NerdMinerV2/1.6.3...

Please, print miner version to console during boot process, it is useful for troubleshooting....

UPDATE. My device TDISPLAY v1.14 hashes at 55 kHps because it has chip ESP32 (reported by esptool flash_id). T-DISPLAY S3 hashes at 78 kHps because it has better chip, ESP32-S3. Mystery solved. Anyway, I would like to have an easy way to verify what firmware is flashed to the device... Maybe that my device is not v1.14, I have it for some time and PCB has label 19-6-20 V1.1 XY-CP...

Hi! Thanks for this information. I'll try what happens related to adding the version as a parameter on the public pool. I'll add version to log too

Regarding hashrate is exactly what you said, regarding adding ESP32 processor. ESP32S3 has IRAM and this brings NerdMiner faster response on CPU hashing functions

Miner information (version, password) can be seen at this mining pool dashboard

Configuration of NerdMiner to connect to that pool:

{
  "SSID": "myNerdAP",
  "WifiPW": "mySECRET",
  "PoolUrl": "bowserlab.ddns.net",
  "PoolPort": 3333,
  "PoolPassword": "c=BTC,m=solo,d=1",
  "BtcWallet": "1PKN98VN2z5gwSGZvGKS2bj8aADZBkyhkZ.TEST",
  "Timezone": 0,
  "SaveStats": false
}

When you cannot configure miner password (fw 1.6.3 doesn't support it), you can use just "x", it looks like pool remembers coin that was mined in the past for that address...
