[Ovmsdev] Problems ms_v_charge_mode

I can’t repeat the issue. Here is what I did:

Bring your vehicle_kiasoulev into the latest build tree for ovms v3.

Change
#include “esp_log.h"
to
#include "ovms_log.h"

Remove:
MyEvents.RegisterEvent(TAG, "ticker.1", std::bind(&OvmsVehicleKiaSoulEv::Ticker1, this, _1, _2));

and change:
OvmsVehicleKiaSoulEv::Ticker1(std::string event, void* data)
to
OvmsVehicleKiaSoulEv::Ticker1(uint32_t ticker)

Add an ESP_LOGI diagnostic trace to Ticker1 and SetChargeMetrics

In the constructor, set:
ks_charge_bits.ChargingJ1772 = true;
ks_charge_bits.ChargingChademo = true;
and removed the comment-out in SetChargeMetrics

Here is the output that I get:

OVMS > level info
Logging level for * set to info

OVMS > vehicle module KS
I (9235) v-kiasoulev: Kia Soul EV v3.0 vehicle module
I (10035) v-kiasoulev: Ticker1 ks_charge_bits.ChargingJ1772=1 ks_charge_bits.ChargingChademo=1
I (10035) v-kiasoulev: SetChargeMetrics V=230.000000 C=0.000000 CL=28.695652 CHADEMO=0
I (10035) v-kiasoulev: Aux Battery voltage low

OVMS > metrics list v.c.mode
v.c.mode                                 standard

OVMS > metrics list v.c.type
v.c.type                                 type1

OVMS > metrics list v.c.vol
v.c.voltage                              230V

Are you sure you are running against the ‘latest’ openvehicles/esp-idf (2.1 branch) and openvehicles/ovmsv3 (master branch)?

You can try to menuconfig Components -> ESP32 -> Panic Handler Behaviour -> Invoke GDBStub (to get a better stack trace and diagnostic capability).

Going forward, it is probably easiest to merge in what you have with our master github, and tidy up the integration a bit (stuff like the ovms_log.h not esp_log.h, the Ticker1 event, etc); that way we keep you up-to-date with framework (in particular vehicle.{h,cpp}) changes. Shall I do that now? Based on your master or pr/5 branch?

Regards, Mark.
