[Wayne Love]

Using Leafspy I can see that it's using the following poll and response to get the SOH of the batteries 1742706668.884315 1R11 79B 02 21 61 00 00 00 00 00 1742706668.892602 1R11 7BB 11 4b 61 61 1a cc 23 70 However, when try to do the same poll with OVMS using the following code... static const OvmsPoller::poll_pid_t obdii_polls[] = { // BUS 2 { CHARGER_TXID, CHARGER_RXID, VEHICLE_POLL_TYPE_OBDIIGROUP, VIN_PID, { 0, 900, 0, 0 }, 2, ISOTP_STD }, // VIN [19] { CHARGER_TXID, CHARGER_RXID, VEHICLE_POLL_TYPE_OBDIIEXTENDED, QC_COUNT_PID, { 0, 900, 0, 0 }, 2, ISOTP_STD }, // QC [2] { CHARGER_TXID, CHARGER_RXID, VEHICLE_POLL_TYPE_OBDIIEXTENDED, L1L2_COUNT_PID, { 0, 900, 0, 0 }, 2, ISOTP_STD }, // L0/L1/L2 [2] // BUS 1 { BMS_TXID, BMS_RXID, VEHICLE_POLL_TYPE_OBDIIGROUP, 0x01, { 0, 60, 0, 60 }, 1, ISOTP_STD }, // bat [39/41] { BMS_TXID, BMS_RXID, VEHICLE_POLL_TYPE_OBDIIGROUP, 0x02, { 0, 60, 0, 60 }, 1, ISOTP_STD }, // battery voltages [196] { BMS_TXID, BMS_RXID, VEHICLE_POLL_TYPE_OBDIIGROUP, 0x06, { 0, 60, 0, 60 }, 1, ISOTP_STD }, // battery shunts [96] { BMS_TXID, BMS_RXID, VEHICLE_POLL_TYPE_OBDIIGROUP, 0x04, { 0, 300, 0, 300 }, 1, ISOTP_STD }, // battery temperatures [14] { BMS_TXID, BMS_RXID, VEHICLE_POLL_TYPE_OBDIIGROUP, 0x61, { 0, 300, 0, 300 }, 1, ISOTP_STD }, // SOH for AZE1 POLL_LIST_END }; It results a CAN bus error 2025-03-23 13:48:10.648 AEDT E (11528) esp32can: can1 stuck bus-off error state (errflags=0x00040cab) detected - resetting bus I'm new to this but from what I can work out what I am doing should work. Any suggestions? Thanks Wayne
